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.
