PARKER HERL Dual Position Control Valves S4AD Solenoid Valve

PARKER HERL Dual Position Control Valves S4AD Solenoid Valve Designed to eliminate the damaging effects of hydraulic shock caused by liquid deceleration, vapor propelled liquid slugs, and condensation induced hydraulic shock, the S4AD, CK-2D, and CK-6D combine the features of hot gas/ soft gas valve configurations and suction stop with equalization valve configurations. The S4AD can additionally be used for high pressure liquid make up applications to prevent liquid hammer, replacing parallel liquid line solenoid valves. The CK-2D and CK-6D are low pressure drop, gas powered suction stop valves, for low temperature ammonia, approved CFC, HCFC, or HFC refrigerants and corresponding approved refrigerant oils or fluids. The CK-2D is a normally open valve, which uses discharge gas to power the valve closed. The CK-6D incorporates a fail safe feature, which holds the valve in the equalizing position until a safe coil pressure is reached, should a power failure occur during the defrost cycle. The valve position is controlled via the sequencing of two integral pilot solenoids and can be held in a closed, partially Specifications open ( approximately 10% of full flow) or fully open position. By sequencing the solenoids based on time, users have the flexibility to set each stage to meet their specific needs.
