YH230MX Pneumatic no noise pilot-operated - Regulating valve - 浙江众源自控设备有限公司

Product Characteristics

The valve with a S type flow way and a guide wing that im- proved the fluid balance around the cage makes the low pres- sure loss, large flow, wide adjustable range and high-precision flow characteristic

The pilot-operated plug for small-scale adjustment is added to normal Cage guided Valve to improve the whole adjusting capacity

The Pilot-operated valve with high sealing, strong cut-off
capacity and easy operation allows the valve used as vent cut
off valve

large Cv value, and of dynamic stability.
It is suitable to a variety of heavy duty services.

The use of double-layer porous cage and porous valve seat
greatly improves the noise reduction performance of internals
