The Type-710 Back Pressure Regulator is a high flow, highly accurate pneumatic relief valve with an adjustable set point. It's primary function is to provide protection against over pressurization in the downstream portion of a pneumatic system. This precision unit is capable of handling flows up to 50 SCFM. A rolling diaphragm provides the sensitivity that causes the Type-710 to vent to atmosphere in response to the slightest upstream changes.

Features

• Sensitivity - Provides quick response to controlled system pressure variation.
• High Flow Capacity - Flows up to 50 SCFM (depending on set point pressure and port size).
• Compensating Flow Control - Venturi type velocity pressure tube adjusts main control valve opening in accordance with velocity pressure variations of flow from controlled system.
• On-Line Maintenance - Unit can be disassembled and serviced without removing from the air line.

Applications:
The Type-710 is used in place of a standard relief valve to provide protection against excessive build-up in supply pressure lines to instruments and other sensitive control devices. The most common application is to control the air pressure in a system supplied by a compressor. Used in conjunction with a diaphragm operated inlet restricting valve and a bleed orifice, the Back Pressure regulator relieves excess compressor pressure while activating the intake restricting valve. When the regulator shuts off, the down-stream air vents through the bleed orifice allowing the restricting valve to open.
