A direct equivalent of the Rego A3212RT175 valve, ensuring international quality standards and easy replacement. A poppet closure and centrally positioned stem provide fast pressure equalisation and reliable flow isolation. Cable and pneumatic actuation are available.

Advantages

Full compatibilityA direct equivalent of the Rego A3212RT175 for easy replacement and spare parts availability
Dual controlMechanical cable control for emergency or manual closing, plus pneumatic remote control
Built-in excess flow valveAutomatic emergency closure when the flow rate is exceeded, essential for safety if a line ruptures
Reliability and safetyClass A leakage performance and 2.5 MPa (25 bar) operating pressure ensure a tight seal when closed. All critical components are protected by the body inside the tank
Automatic closingThe return spring closes the valve automatically when the control is released or pneumatic pressure is lost
