A gas valve is a tool or apparatus, which controls gases like
liquid propane as well natural gas. Gas valves are used for a
number of applications. These are available in a large number of
inlet, outlet ports, sizes flows and pressure ratings. These may
made of plastic like chlorinated polyvinyl chloride,
polytetrafluoroethylene, polyvinyl, or metallic elements like
bronze, brass, steel, copper, iron, aluminum. What types of gas
valves are found? Electrically actuated ball, Solenoid,
elliptic, proportioning, pinch, check, elliptic, diaphragm,
metering, plug, needle, pressure relief, and stopcock are all
kinds of valves with dedicated features to select. Valves come
together with diverse types of salient substances. A few of
these are EPDM, FKM, NBR, and PTFE. NBR is the commonest sealant
and it is used for 0 to 180 degrees Fahrenheit temperatures.
EPDM is for a number of fluid and hot and applications in a
range of -10 to 300 degrees Fahrenheit the temperature. FKM is
particularly for hydrocarbons like gasoli
