Characteristics: - RAK are servo-operated valves normally open and pneumatic closed, by means of refrigerant gas acting upon power piston,taken from external high pressure line through a solenoid valve VMP10 type, available by order.

- RAK valves are designed to use with ammonia and other common fluorinated refrigerants,for use in suction lines or any application that need a valve normally open with automatic closing for short period. - RAK valves can operate with △p=0 and in any position.

But when the valves are closed or open, there isa bleed of gas around the piston to allow open the valve when the high pressure gas stream is closed. - The connection between solenoid valve and RAK valve is through nut & nipple union on the bonnet, and cooper or steel pipe DN 1/4" or 3/8"brazed or welded to nipple.

Works ).Applicable to all general-purpose refrigerants and non-corrosive gases and liquids, including ammonia, fluorine, propane and propylene. · Perfect sealing performance. The moving part valve stem is provided with high-precision double O-ring and PTFE packing to ensure zero leakage.

All sealing gaskets are environment- friendly asbestos-free ones that are resistant to both fluorine and ammonia. · The back seal design enables convenient valve maintenance during system operation.

The double-cone seal design ensures large flow capacity, small pressure drop and high efficiency.A special linkage structure between valve stem and valve clack is adopted so that the concentricity of valve clack is adjusted automatically to ensure valve closing tightness and minimize valve clack friction for prolonging service life.

· Compact structure, small size and light weight. Reducing freight cost, shortening installation time and lowing labor intensity.Best protection against rusting and corrosion. Special rust-proof materials are used on the surface.

The internal and external surfaces are treated with special formula and process to ensure cleanness and rust-free. The stainless steel valve stem is polished by a special technique. · Possibility of direct welding to steel pipe or brazing to copper pipe.

Customer options are offered for either hand-wheel or sealed cap.Each valve is inspected strictly according to European standards.
