  • Test pressure for valve body: 21 kgf/cm2
  • The inlet pressure gauge indicates pressure before relducing, and outlet pressure gauge indicates pressure after reducing
    •When cleaning the impurities on the filter net, just take off the cylinder (component 4), then filter net (component 7) can be unloaded at the same time.
  • Adjustment range :
    1kgf/cm2 ∼ 3.5kgf/cm2
  • Applied temperature :-15℃∼80℃
  • Maximum applied pressure: 12 kgf/cm2

Pressure Reducing Valve Set Functional States Chart

  Open state
When the handle is rotated upward, pressure reducing valve set becomes pressure reducing (open) state.
  Bypass open state
When the handle is rotated to horizontal position, pressure reducing valve set becomes Bypass open state.
Closed state
When the handle is rotated downward, pressure reducing valve set becomes pressure closed state.
