Hansen Technologies Corp.: Gas-Powered Two-Step Suction Stop Valve
January 3, 2011
The Hansen HCK5D is a heavy-duty, gas-powered 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.
