Product Description:

Ball Valve For Heating Supply

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.

Q:01 civic valve question?
1.7 SOHC VTEC? I thought that used hydraulic lifters with the small flat plates under the lobes like a subaru or the DOHC older style hondas no? Otherwise i've never adjusted those valves unless they are the same as my old engine like a 1.6 SOHV ---V for valves Where you adjust the top screw and loosen the nut then adjust with the guage. Question are you useing the manual while adjusting from Honda? You can't just take the valve cover off and start sticking the feeler guage at every spot, Do know where each piston is at and at what stroke? also don't get the adjustment wrong for EX. and IN. side because that will just mess everything up even more. Is it high mileage also? and if you know you did it right and it still sounds loud you might have a bent valve or just engine damage like piston slap or something else. I've never had to adjust the valves for that vehicle in all the years i've worked on hondas or acuras, even though they say to adjust every 100k or something we've never had one that was really loud in that model plus those engines are dirt cheap and easy to swap if any engine damage is done... But ya, the honda manual is best for step by step instructions specially when you have to check certain ones at certain piston positions and after you can learn a trick to do it even faster and you can check a few at the same time then turn the engine and check the other ones but theres not enough space to explain in detail if you don't know.... Good luck though....( and do not leave the guage under the valve while your tightening the bolt down, you will squish the guage and then your specs will be off to )
Q:Is valve standard of API and ISO same?
the name itself suggest that it isn't. BSP covers only pipelines but ISO is a standard concerning different materials, processes, programs and quality policies.

Q:what happen when solenoid valve is activated?
If the pressure in any one zone is different than the other zones it could be one of two reasons; either the pressure is high (usually due to one or more sprinkler heads not poping up), or its low (usually due to a leak in the pipes). Something that could cause low pressure in all the zones are an obstruction in the water line above the valves (unlikely), or a hole in the line above the valve (the water would be filling the valve box and causing damage to the lawn wherever it is located), or leaks in all the lines (again would be easy to identify from the excess water in the ground at the source of the leak). Lastly the valve itself could potentially be faulty. The solenoid inside the valve holds the valve open when electricity is applied across it. If the wires to it are damaged; if the solenoid is bad; or if the valve has any rust or dirt inside that could cause a lower than normal amount of water flow.
Q:Cam carrier/ valve gaskets replacement?
valve cover shouldn't be that much of a problem as long as you have some basic tools and some mechanical ability. Take it that its a 4 cylinder car, the size of the motor is very helpful when looking for tips. Just don't over torque your bolts when replacing. 89 in lbs is about normal on gm's valve covers
Q:Is it possible to reduce pressure, using a valve?
One control valve can reduce pressure, as long as there is always a significant flow through it. The main reason for using more than one valve is usually to reduce or prevent cavitation caused by a large pressure change through a given valve. Ethanol has a pretty high vapor pressure, so cavitation might be a problem. Control valve manufacturers usually provide design guides for their valve trim choices (often in software form) that lead you through the choices and requirements. Each valve design has different limits. But, my seat of the pants feel is that you can do this with one valve. I have included an example. I am not specifically recommending this company. -- Regards, John Popelish
Q:Explain how a valve works. What is the difference between in ATC, ATO, FO, FC, and FLP(Fail last position)?
THere are a large number of types of valves; ball, gate, globe, needle, etfc. I suggest you look up valves on wikipedia. ATO = air to open; the valve has a pneumatic operator with a spring returning it to closed when the air pressure is removed ATC is the reverse FO = fail open; if the actuator fails the valve will be open. Actuators are made ATO, ATC, and air to move either way [no spring]. The latter would be your FLP. Control valves, by which I mean a proportioning valve or valve with a variable open area, with a 3-15 psi control input, are usually ATO.
Q:Can any one tell me how can i make a one way valve at home?
We need to know what exactly the work/purpose your 'one way valve' has to perform. You have given overall description that got you fairly good answers here. But if you really want to solve a problem by yourself (instead of going to any plumber) then you have to understand that the one way valve used for garden drainage system is different than the swimming pool drainage system and numerous other household applications one can think of where 'one way valve that would allow water or other fluid one way but if there is too much pressure on the opposite side the valve will close and stop water from flowing backward'. Let me assume that you are in a place where neither plumber nor the hardware shop is readily available. In that event you may consider placing one ‘flap-valve' on top of the outlet pipe. The valve is simple metallic piece may be from tin, iron, plastic etc., that can withstand the force applied by water/liquid on it. The flap-valve would have to be hinged hanging from top part of the drain/pipe in a way that it can move away with the pressure of the inside tank or reservoir and then would shut-off when reverse flow (RF) would occur, by the force created by the RF. If you have seen any Tube Well or DWT Pump then you may notice that these are also having a RF (Check Valve) mounted either at the bottom of the sunk-pipe or somewhere in-between. This help in having the flow of ground water upward only and any reverse flow back to the ground is automatically restricted as the 'flap' would fall onto the pipe orifice due to gravitational weight as well as weight of water column on top of it. Hope this would help learn the basics.
Q:Sound when I open or close rain bird sprinkler valve?
It could be the solenoid. It could be actuating very slowly and hammering when it tries to shut off. The solenoids are only $5 or $6. Not a significant expense. I just had to replace an entire valve. Not costly but a good size hole while I was working on it.
Q:1999 Pathfinder Suction Control valve?
hold the computer near the Pathfinder it will suck data directly off the internet (NO WAY) what you need is a complete diagnosis by a experenced Technician or a Nissan Technician. Idle control is on the bottom of the throttle chamber or on the intake manifold. Stalling and Dieing may be caused by a Distributor or air flow meter fuel pump or clogged up fuel filter.
