1/2" to 3" Adjustable Stroke ( Factory set at 2" )

Key Benefits: Precise Superheat Regulation: The ZP thermostatic charge provides stable refrigerant metering across low-temperature ranges (0°F to -40°F)

Industrial Construction: Designed for heat pump refrigerant flow control with a focus on long-term seat reliability and minimal pressure drop

Tamper-Resistant Design: No adjustment knob ensures that critical safety and high pressure limit settings remain exactly where the technician set them

allowing for rapid equipment heat-up and improved heat transfer efficiency
