‧Module assembly, which means light structure,
　space-saving, easy installation and maintenance.

‧Equipped with buffer check valve, unfavorable
　effect from water impulse can be eliminated.

‧Simple structure, precise tuning and easy operation.

‧Module assembly can decrease leakage coming from
　assembly connections due to long-term vibration.

　　　　　　Outlet pressure gauge 　Inlet pressure gauge


‧Adjustment range : 0.5kgf/cm2 ~5kgf/cm2
‧Applied temperature : -15 ~ 80℃
‧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.

Pressure Reducing Valve Set Functional States Chart

Open state



 		ON　

When the handle is rotated upward, pressure reducing valve set becomes pressure reducing (open) state.
Bypass open state
PASS　

When the handle is rotated to horizontal position, pressure reducing valve set becomes Bypass open state.
Closed state


 OFF　

When the handle is rotated downward, pressure reducing valve set becomes pressure closed state.
