Variants
The direct acting pressure reducing valve feeds a secondary branch of a circuit at
a lower pressure than the main branch, guaranteeing minimum variation of the set
pressure with flow alterations of up to 20 l/min.
Slight leakage is tolerated for this type of valve.
It raises the safety level with the RELIEVING system that enables fluid to pass
through the valve from PR to T, preventing pressure increases in the controlled
branch and protecting the load, and by making it impossible for plant operators
to set a higher pressure rating than that specified in the catalogue. It has a pack
spring with mechanical stop.
It has a galvanised steel body. The plunger is in tempered and ground steel.
