PCV series, Pressure Regulating Valves
Valution`s pressure regulator of the PCV series is distinguished by having the internal structure of the piston & cylinder and the internal structure of diaphragm type in the pilot type.
It is also possible to produce a direct acting, not a pilot type.
The primary pressure adjustment function(pressure relieving) and the secondary pressure adjustment function(pressure reducing) respectively may be performed separately.
Sensing method is standard in 'integral type', and 'external type' can be custom-made.
This pressure regulator is a self acting pressure regulator that maintains a fixed value according to a set pressure value without transferring power from the outside.
Actuator can be a spring loaded diaphragm or cylinder type, which installed on the valve body. The valve body is a straight globe pattern casted steel.
