White Knight Pressure Regulators

Automatically Control System Pressure Without Additional Circuitry or Feedback

PTFE Pneumatic Pressure Regulators

White Knight forward-pressure regulators and back-pressure regulators offer remote piloting capability to maintain system pressure for high-purity chemical circulation loops and systems with multiple tool drops or dispense points. They feature fully-swept PTFE and PFA flow paths. They operate at up to 100°C (212°F) and 7 Bar (100 psi). They are air-spring loaded, highly accurate, and reduce system pulsation. Pressure regulators are available in 1/2-in, 3/4-in and 1-in models — determined by the connection size and outer diameter of the tubing. The flow through, or inner diameter of the tubing, is 1/8-in smaller than the connection size.

iPolymer PTFE Manual Pressure Regulators

iPolymer forward-pressure regulators have a PTFE wetted flow path for use in DI water, aggressive chemicals, and corrosive media. They are ideal for high-purity processes in solar, semiconductor, pharmaceutical and chemical process applications. All configurations are fitted for panel mounting simple adjustment knob to control fluid pressure at the outlet. The PTFE-coated stainless steel adjustment screw is configured for low torque, reliable manual operation. They are available in two factory-set regulating options 0-40 or 30-60 psi.
