Several representative reduced pressure pneumatic valve type ( Figure)

the typical vacuum pneumatic valve what kind of models are there? As follows:
piston vacuum pneumatic valve type, brass nickel plated, PN, export pressure 。 Any adjustable bar, the most compact in the import vacuum pneumatic valve type, the most valuable, can connect pressure gauge, is widely used in high-rise building branch decompression;
piston vacuum pneumatic valve type, brass material, with Windsor knot head, easy to install, PN, outlet pressure. - 。 Bar arbitrary adjustable, can connect pressure gauge, is widely used in high-rise building of branch pipe and main relief;
diaphragm vacuum pneumatic valve type, brass material, PN, outlet pressure. - Bar arbitrary adjustable, can connect pressure gauge, is widely used in high-rise building of branch pipe and main relief;
diaphragm vacuum pneumatic valve type, brass material, PN, export pressure Bar arbitrary adjustable, can connect pressure gauge, is widely used in high-rise building of branch pipe and main relief;
pneumatic valve diaphragm type low pressure reduction model, brass material, PN, export pressure The bar arbitrary adjustable, can connect pressure gauge, is widely used in precision equipment, and breeding rooms and laboratories;
used for pipeline pressure relief, in the case of local high pressure or sudden pressure, protection of later life, production water.
high-rise building water supply, solar water heaters, water supply system, form a complete set of equipment and so on.
