Category of:Pneumatic control valve
Product Name:Pneumatic diaphragm single seat control valve
Product introduction:
With the top guided structure pneumatic diaphragm straight-through single seat control valve is equipped with multi spring actuator to present compact structure light weight flexible action S streamline flow small pressure drops loss large capacity accurate flow characteristics convenient disassembly etc. which is widely applied in precise control services such as gases liquids and other media whose technical parameters include pressure flow temperature liquid level maintained at a given value. The valve is especially suitable for the working occasion of small allowable leakage small pressure drops in front and back of valve.
1.The metal plug is suitable for various occasions to meet IV leakage standard and ZXPQ soft seal plug reaches up to VI leakage standard.
2.As bellows seal control valve fully sealed of moveable stem is formed to avoid fluid leakage.
3.With thermal insulation jacket control valve is applied in the occasions of crystallized fluid solidified jam.
