Bottom valve A3212R250 DN50 PN 2.5 MPa

The A3212R250 has no built-in excess flow valve (T — Thermal), as reflected in its model designation. Its primary function is high-capacity shut-off control. It does not close automatically in an emergency when the flow rate is exceeded.

Description

The A3212R250 DN50 bottom valve is a high-capacity shut-off device for road tankers, trailers and semitrailers carrying LPG (propane/butane) and anhydrous ammonia. A direct equivalent of the Rego A3212R250, it offers the highest flow capacity in the 2-inch range. Its poppet closure reliably isolates flow, with cable or pneumatic actuation.

Advantages

Maximum flow capacityHighest flow in the A3212 series with a 2" threaded connection, speeding up loading and unloading
Full compatibilityA direct equivalent of the Rego A3212R250 for easy replacement and spare parts availability
Dual controlMechanical cable control for emergency or manual closing, plus pneumatic remote control
Easy servicingA replaceable nickel- and chrome-coated seat insert permits repairs without replacing the valve body. Stainless steel fasteners resist corrosion
Reliability and safetyClass A leakage performance and a 2.5 MPa (25 bar) operating pressure ensure a tight seal when closed. The body protects all critical components
Automatic closingThe return spring automatically closes the valve when the control is released

Applications

Road tankers, trailers and tank containers carrying LPG and anhydrous ammonia where high flow rates are required
Stationary above-ground liquefied gas storage tanks
Liquid- and vapour-phase withdrawal systems
