Overview
ControlAir Type 710BP Series 429-829-087, 710-DA Precision Back Pressure Regulator
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.
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.
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 downstream air vents through the bleed orifice allowing the restricting valve to open.
