Barksdale Pressure Switches ~ Diaphragm Style

Barksdale Diaphragm Pressure Switches


Barksdale's Diaphragm Pressure Switches offer superior accuracy in a robust package, making them the ideal solution to your industrial pressure
control needs. Diaphragm switches are ideal for applications demanding instrument class accuracy and where pressure pulsations are less than 25 cycles per minute. Available in various pressure ranges up to 150 psi, diaphragm switches are suitable for use in either positive pressure or vacuum applications. Single, and dual, and triple circuit models are available.

Housed models (D1H & D2H) feature a durable, anodized aluminum enclosure with an integrated 1/2" NPT conduit connector,a tamper-resistant cover for the setpoint adjustment screws, and are rated to NEMA 4 as a standard. For applications requiring a highly accurate switch in a durable package, Barksdale's Diaphragm Pressure Switches are the ideal choice.

Coax Valves for Flow Control

Coax Valves from Anderson-Bolds

For over 45 years, the coaxial valves developed by our company have formed a tried and tested element in the control of vacuums and gaseous, liquid, gelatinous, abrasive, contaminated, and aggressive media.

The coaxial valve design allows - as compared to conventional valves - high pressure media to be controlled at high flow rates. Our coaxial valves are available in 2/2 way or 3/2 way versions with threaded or flanged connections. The valves are actuated either by direct-acting solenoid or externally controlled.

  • high cycle life
  • fast actuation
  • compact design
  • maintenance free
  • bi-directional flow
  • pressure balanced
  • back pressure tight
  • installation position optional
  • valves operate from 0 bar upward
  • application with contaminated media
