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:Pinch Valve?
a pinch valve has a membrane (or sleeve) inside the valve. When the valve handle is screwed down the membrane is pinch closed. This type of valve is good when the flow needs to be finely controlled. It is also good for slurry (abrasive) flows, as the membrane can be replaced when worn. Gate valves are less effective when the flow must be controlled. They are not used in slurry applications at all, as the gate will be quickly worn away. Knife gate valves can be used in slurry, but are generally totally open or totally closed. The valve must be installed the correct way around, as when closed the weight of the product against the knifegate helps seal the valve. If you have the wrong way around it will tend to leak.
Q:i'm being charged $300 to replace a 75gallon water heater valve, is that too much?
Plumbers and service companies usually have a minimum trip charge for a service call to cover their profit and overhead for the time to drive out there and sometimes include the first hour of labor. They usually will mark up the part they install as well, sometimes 100-300% depending on how they do business. Then you have to pay the labor over what the initial trip charge covered. My plumber charges $120/hr which includes a helper, so $300 adds up real quick and may not be all that crazy of a price to pay. Also, they charge a convenience fee on holidays and weekends. If you cant do it yourself, you are stuck with paying others. Always use someone elses recommendation for plumbers, carpenters, electricians, etc. or you may get taken advantage of.
Q:PCV valve = oil burning?
The PCV valve is a possibility but the more probable cause on your car is that the spark plug tube seals are leaking oil. The 4 cylinder hondas have tubes that surround the spark plugs that run from the valve cover to the top of the cylinder head. There are gaskets on the valve cover to keep oil from getting into the tube from the top and seals at the bottom to keep oil from getting into the tubes from the bottom. on older hondas the tubes fill up with oil and the oil works its way into the engine combustion chambers through the spark plug threads. its real easy to see if this is the problem. Usually you can just pull each of the spark plug wires off. If the end of the spark plug wire is wet then you have leaking tube seals. Typically the seals on the valve cover can be replaced for about $50. if it requires the lower seals its pretty pricy. I think that's what you're going to find. PCV failures are rare as are valve seal leaks or internal engine wear problems on hondas. hope that helps hope that helps
Q:Wall Heater question? (Gas Valve)?
Depends on what kind of wall heater. FOR A 24 volt system : you will need a ohm/volt meter to do that. Make sure the thermostat is calling for heat, and the gas going to the unit is on. you should have 24 volts at the gas valve. if there is 24 volts there, and the burners are not on, then the gas valve is bad. If you don't have 24 volts there, then your thermostat could be bad, and not turning on the gas valve, or you might not have control voltage. You should be familiar with basic electricity to do this.

Toro Irrigation Valves
Q:EGR Valve drivability issues?
EGR - Exhaust Gas Recirculation The EGR opens controls a valve that connects your exhaust manifold to your intake manifold. The EGR valve reintroduces engine exhaust back into the cylinders to reduce combustion efficiency during high rpms. This is to protect the engine and keep it from overheating. If you EGR is acting up and opening on low rpms then the car will spew out smoke due to unburned fuel and suffer from loss of power.
Q:how to replace 1991 honda accord heater control valve?
Do it from underneath. Drain the cooling system and cut the short hose between the heater core and the valve with a sharp knife. Unfasten the actuator cable, loosen the clamp on the heater hose and work the heater hose off it. Use the sharp knife to slice the remains of the short hose off the heater core... be gentle because the soft pipe is easily deforned (which is why you must not try to wrench it off). Put a replacement hose on the new valve and reassemble. When you refill the cooling system be sure to purge the air by opening the bleeder nipple on the upper radiator hose housing at the engine until a steady stream of coolant comes out. Watch out for the sharp edge of the catalytic converter shield! I have a scar on my wrist from learning that the hard way. EDIT - I forgot to mention - if the cable seems to be misadjusted on the valve when you are done, remove the passenger side of the console and look at the mixer linkage in there. The cable housings often slip in the clamps.
Q:Removing washer hoses from shut-off valves......?
Hold the valve with a pair of pliers and use another pair to loosen the hose connection. This will prevent twisting the valve and its piping. You could spray a little wd-40 on them first.
