PRV25

The ADCA PRV25 is a series of direct acting pressure reducing
valves designed for use on steam, compressed air, water and
other gases and liquids. These regulators are suitable for reducing
steam pressure at the point of use on laundry machines, dyeing, food
industries, sterilizers, etc.

Compact design.
Bellows specially designed for high durability.
Non-rising adjustment knob.
Lockable knob system.
Built-in strainer
