Product Description of Ball valve for heating supply:
Technical introduction
★The ball valve is designed as fully welded structure,which can prevent the leakage of medium.
★The valve seat is floating and spring-loade.The seal is made of soft seal materials of PTFE+20%C and Viton B.The seat is tightly abutted against the ball surface by the pressure of a spring,so that even if the media is in low pressure,a reliable sealing can be assured for the ball valve.Double piston effect and double seal(two-seal seat)are adopted in specially designed valve seat to realize double sealing,which makes the tightness of the ball valve more advantageous and the operation easier.
★A floating ball is adopted for DN15-DN200,and a stem and trunnion ball is adopted for DN200 and above,which can ensure the accurate position of different size ball.In other words,the sealing performance,low torque valve and operability can be guaranteed.
★The sealing of the stem is fulfilled by two replaceable O-rings and packing consisting of PTEE+20%C or flexible graphite,as the packing seal material,is fire proof effect,and is specially suitable for fuel gas systems.
★The materials used for the valve body and pipelines are the same(carbon steel or SS steel),valve body and stem adopt SS steel and the packing adopts PTEE+20%C which is corrosion-resistance or flexible graphite.

Features and Applications
Raymond's fully welded ball valve for heating supplyand Fuel Gas systemare used to control the flow at fully open or closed position,not regulate the flow.Only special types of ball valves can realize the flow regulation.Therefore,our welded ball valves can satisfy the requirements of heating systems,e.g:
★Main pipelines of heating equipment
★Cross channels of heating pipes
★Heat exchanger station and any long distance operating station,e.g:
For the transmission of hot water and two kinds of mixed media(water,air or natural gas),limited to Max.4.0MPa and 200°C.
For the transmission of natural gas and one medium,from -30°C to 60°C,and even up to 150°C using specially designed ball valves.
★Coal gas pipelines,trunk and the branch supply lines.

Q3:How can I place an order?
The only one thing you should do is to tell us the sepecification about type 、quantity and mode of transportation, then we will send you quotation within 24 hours.
- Q:It's filling up a 5 gallon bucket roughly ever 9-10 hours. It was leaking with an old valve and has been replaced, and after being replaced it didn't stop. The temperature has not been adjusted higher or lower, it's exactly where it was for the year before the leak started. Any ideas?
- Mike, Since you haven't raised the Temperature setting on the heater which could cause this problem, you either got a bad replacement p/t valve OR maybe it was a cheepo. If that's the case, I would replace it with a good brand return the other one after you find the new on works right.
- Q:So I know the main purpose of the EGR valve is to recirculate some exhaust to the cylinders to reduce NOx emissions. However, a mechanic told me that a malfunctioning EGR valve can make the engine run way hotter, and that this can damage the pistons, or other components of the engine, over time. Is that true?
- Well some what true an egr mifht create a vacuum leak making the engine run faster but to burn a piston it woul have to be close to the cyl like a intake leak easy way to check for vacuum leaks is to take a can of carb clean and spray down the intake and listen for idle change (don't spray dist)
- Q:how to get adjust the valves on a craftsman mower with a briggs and stratton with ohv 18hp? Iv'e heard you adjust them around 5 thousands with a feeler gauge. But im confused about what position to adjust them. Iv'e heard you wait till one of the valves is closed while the other is open and adjust that one. Then repeat till you got them adjusted. Whats the proper way?
- I have never worked on the lawn mower engine. I have adjusted valves on motorcycles which have overhead valves. There are markings on the ignition generator that designate which valve would be in the correct position. However, if you spin the crank which will move the valves up and down, you can adjust each valve when you can shake the valve tappet. This happens when the valve is closed and the cam comes away from the tappet. You should be able to feel play in the tappet when the valve is closed. Adjust this closed valve. Be careful not to make your clearance to tight. This is worse than loose. Looseness makes noise and excessive wear over time but tight will burn your valve seat and ruin the valve. I have to wonder if you really need to do anything to valves on a ten year old tractor. It's only a tractor, not anything high revving or high performance. My tractor has overhead valves and was new in the early 90's. Never did anything to it but change the oil. If you do plan on doing it, good luck.
- Q:what exactly causes a valve to stretch?
- All metal bend and even wear down. Valves don't stretch. They wear down. Good Luck...
- Q:What are the requirements for valve automation?
- Some valves are controlled to maintain a fixed pressure on a system. Others control the level in a tank or vessel while still others actually control the flow rate in a pipe or line. The automatic control of flow through a valve requires a sensor to determine if flow is needed or what the flow rate is. You then need a controller to take this input and then adjust the valve to achieve the desired result. This is called a control loop. Some are all electric/electronic while others are all pneumatic. The valve itself is a specific valve designed to perform the function intended. It is not a good idea to take an existing on/off valve like a gate valve and try to control flow. These type of valves do not have a flow characteristic that is proportion to valve opening while a control valve does.
- Q:P.S.V. Pressure Safety Valve
- They okorder or other relief valve sites for more information.
- Q:If my understanding is correct, in a standard combustion engine as you press the gas pedal the speed of everything increases: the cam shafts spin faster (and thus the valves move faster), the pistons move faster...EVERYTHING goes faster. That sounds like an optimal system in theory, so what is the benefit of having the valves be able to be intelligently out of phase (for lack of a better phrase) with the rest of the system?
- Thinking of time, the valves are open longer during engine idle and much less at higher engine speeds. Now think of a small block chevy where we can change engine timing a little bit advanced or retard which affects power and performance. To make a bigger change, another grind of camshaft has to be installed. This grinding of camshaft is called profile - the characteristics of the lobes size, ramps and direction which work at an entirely different fashion. With variable valve timing, the computer can advance or retard a cam to adapt to many different profiles to provide the best power, torque, economy and lowest emissions possible for any given condition such as cruising down a highway, climbing a long tall hill, or driving light to light through the city. Almost an infinite amount of profiles without swapping out a single camshaft. Seems alot easier and sure is alot cheaper, and we don't have to do the work anymore. Systems are pretty reliable as they typically use engine oil pressure that is directed by a solenoid run the by the ECM on a duty cycle which allows oil pressure to the advance side of a cylinder on the end of a camshaft where the cam is rotated ahead of its resting position thus changing the time the valves are open and when they open. The cam is spring returned to resting position ( some may be hydraulic?) Hope I explained this so it is clearer than mud.
- Q:I have several stations in my automatic lawn sprinkler system. Each station has a valve that contains: 1. Manual Shutoff, 2. Flow Control Knob, 3. Solonid, 4. Anti-Siphon valve. Any way my question is this, Why does water continue to flow even when the manual shutoff is turned off and the flow control is also turned off?
- Any manual shutoff should shut the zone down completely, a flow control will limit the volume of water that leaves the valve by resticting the valve diaphram movement. If neither is working they may not be operational. A zone that continually runs either has a plunger stuck in the solenoid, a ruptured diaphram in the valve, or debris between the diaphram and valve body. If all these are contained in the valve, the most likely cause would be a bad diaphram or debris keeping the valve from closing completely
- Q:I was wondering if the pressure relief valve can be vented right under the house or does it have to be ran to the outside of the house. Also is there another method such as a catch pan that I can employ? I live in Washington.
- it should be run outside but most people don,t even use one. you can get a catch pan that fits under the heater but you,ll have to raise your heater up to install it.
- Q:I had heart surgery a little over a year ago. This surgery gave me an artificial aortic valve in replacement to my real aortic valve. Before this I smoked weed all the time, but now, I 'm on blood thinners, and I'm not sure if it's okay. Is it?
