High pressure diaphragm operated reducing valve for dual pressure systems

Overview

PP901 pneumatic valve controls the pressure of the air delivered to pneumatic control systems. Models available for single-pressure systems or two-pressure systems (Day/Night or Summer/Winter) requiring two independently regulated pressure settings.

Features

• Built-in adjustable safety relief valve for limiting downstream pressure.
• For two-pressure models: Pressure changes accomplished with manual switch or automatically with electric pneumatic switch.
• Adjustable stops for desired settings.
