1 Pressure Reducing (and heck) Valve eatures PRSSUR RU ( ) VV to 8l/min Pa -***-*- R -***-*- Specifications qthis valve is used when part of the circuit uses pressure that is lower than the main circuit. wven when pressure changes in the primary main circuit, the reduced secondary pressure is adjusted automatically and maintained at a constant level. eonnecting a remote control valve to the vent port allows remote control of adjustment pressure. rthe mounting surface of the gasket conforms to the S standards shown in the table below.
