Hansen HCK5D/HCK5DW Gas Powered Two Step Suction Stop Valves
The Hansen HCK5D is a heavy-duty, gaspowered two step suction stop valve which is self-equalizing and includes a delayed opening feature after defrost or a power failure. The HCK5D valve provides an internal, controlled bleed-down (equalize) circuit which will not allow main seat to open until the pressure across the valve is at a lower, safer pressure differential. This is accomplished by a unique, internal bleed-down piston design, thereby greatly simplifying external control valve group piping and reduces installed cost. Valves remain normally open during refrigeration via a spring and require no pressure drop to operate. A higher pressure refrigerant gas closes the valve during defrosting. If loss of power occurs during defrost, evaporator pressure is utilized to keep valve closed until bleed-down occurs.
