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.

                                             

Design Features  of Ball valve for heating supply:

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:Automotive valve question?
a) The very end is the tip. Below that are grooves that the keepers lock into. This is actually the thinnest part. Below that is the rest of the stem. The general name for the largest part in total is the valve head. b) Surface sounds right. Hadn't really thought about it before. LOL c) Valve Guide. These can either be just a plain hole in the cylinder head material, or often they have bronze inserts. Plain Guides are often repaired by a process called knurling. d) Valves seal to the head by grinding each at the same angle, (usually 45 degrees) and then they are lapped which is where an abrasive compound is placed in between, and the valve is rotated. This matches the surfaces more closely yet. The parts that seal are called the valve face and the seat which is actually a separate part that is inserted into the head, and can be replaced. e) Oil is supplied to that general area, by either holes in pushrods that lubricate the rocker arm, or in the case of rockers mounted to a shaft, through the shaft. In the first case, oil is supplied by the hydraulic lifters. In the latter, the shaft pedestals are drilled for oil passages. In both cases, oil is present in the area, but is not applied directly to the valves. In fact, the job of the valve stem seal is to keep too much oil from getting in the guides. f) Usually the coolant flowing through the heads is enough to carry away the heat, although some hi-performance engines employ techniques such as hollow exhaust valves filled with sodium. Most normal valves are solid.
Q:Is my water valve broken?
Being old plumbing, when you turned off the valve (which you did not need to do to work on the drain) debris probably broke loose in the water line. Turn the valve to the off position again. Disconnect the supply tube above the valve. Hold a rag over the top of the valve and turn it on and off a few times. this should tell you if there is a clog and may clear the debris out. Good luck.
Q:Where to get Electric Valve?
Cheapest okorder.com/... Grainger being a major supplier of parts - note the high cost of many of these because of being high temp steam and hot water under pressure and look for other choices.
Q:egr valve replacement?
Why would it. They are from different cars, with different engines.
Q:my water shut off pvc valve will not move to shut off position?
The threads are stripped, you will have to get a new one, until then shut off main line into house if you are flooding
Q:Do blow-off valves cause problems in Audi tts?
Blow off valves are nice, but they aren't terribly good for your car. The main problem is that when the turbo isn't running, that open valve will suck unfiltered air into the engine and can seriously damage it. Blow offs are also pretty inefficient as you lose a good portion of the air in your turbo system. The best thing you can do is just get a good Forge diverter valve. Well made, looks nice, and will add a pretty decent amount of performance.
Q:What is a Valve Job?
a vale job is nothing it means nothing you dont get a valve job you get new heads... are rarely do they cause actual not functioning of the car. you have an old car that has seen better days. and age is catching up to it. the car itself is not the best made car and at best im surprised it hasnt hit the junk pile yet.
Q:Gas safety valve does not work for thick slurries?
Not sure but I would check for corrosion inside the valves. I assume the valves are positioned so that they are not exposed directly to the slurry. If possible, empty the system and test with compressed air to see if the release at the correct pressure. It is very important that this type of safety device work correctly. Also suggest contacting the mnfr. You get what you pay for so I recommend that you do NOT skimp on investment in safety equipment, consider the cost if the safety equipment fails to do what it is intended to do. Killing employees is not very popular with surviving employees and it costs a LOT of money.
Q:32 / 64 / 128 / 512 Valve Car Engine?
:-) Good one! But in case you are serious, number of valves makes sense when connected to the number of cylinders. When some ford puts 16valve decal on the trunk it's completely meaningless because for a 4 cyl engine it would constitute 4 valves per cylinder, for an 8 cylinder engine - 2. So far, the highest number of valves in standard vehicle has been 5. PER CYLINDER. Reasons: 1. enough, 2 - technological.
Q:function of idle air control valve?
The IAC (Idle Air Control Valve) controls the amount of air getting into the throttle body/intake to coincide with the correct amount of fuel to get the perfect fuel/air mixture for proper combustion. Too much or too little air will affect the performance of the engine at idle. If you have the 5.7 350 v8 the idle air control valve is really an easy fix. it sits right in the throttle body and is easy to get to. Autozone in Houston, TX has them for about $22... If you don't get it your idle will be poor and the engine could possible stall at idle.
