Description
Reliable safety relief valve against over pressurization
The Type 710BP 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 710BP 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 710BP 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
