Red Valve Pressure Sensors

Red Valve Pressure Sensors are the industry standard, protecting instrumentation while assuring accurate measurement of slurry and corrosive fluids.  Red Valve Pressure Sensors sense line pressure 360° through a flexible rubber sleeve. The captive fluid is displaced through the pressure sensor body to the instrument's Bourdon tube. All instruments are isolated and protected from the process, so positive and accurate readings are assured.  All Red Valve Pressure Sensors and gauges are proven to offer the highest level of accuracy because they are tested and calibrated through the mid-range.

Factory installed options on any sensor model include:

• Pressure gauges
• Transmitters
• Transducers
• Recorders
• Differential Pressure
• Vacuum Switches

Red Valve Pressure Sensor Models

• Flanged (series 40 and 48W)
• Instrument Protection (series 40w)
• Threaded (series 42/742)
• Wafer (series 48)

Red Valve Pressure Sensor Benefits

All Red Valve Pressure Sensor models protect and isolate instrumentation. Each series is designed to maximize benefits for specific requirements.

40/40w/48w series:

• Full 360° pressure reading
• Self-cleaning flexing action
• Will not clog like traditional diaphragm seals
• Excellent pump protection

42/742 series:

• Series 742 can be flushed or rodded clean without removal from line or disassembly
• Protects from chemical or slurry plugging
• Lower installation and operating costs

48 series:

• Wafer design reduces costs
• Fits 150 and 300 ib. flanges
• Light weight design
