Solenoid Valves - Normally Closed

HS6 4mm Solenoid Valve

HA00606_

Introduction
This flanged, industrial refrigeration duty solenoid valve is very simple and compact but rugged in construction. Body is plated steel alloy with a direct lifting stainless steel plunger that contains a teflon seat that closes on a stainless steel orifice. When electrically energized, seat opens wide; when de-energized, it closes to stop flow in the arrow direction on the valve body.

Applications
This small, direct lifting valve is used primarily as a pilot for various larger gas-powered or liquid powered main valves, as a remote pilot for back pressure regulators or other devices, or as a liquid stop valve for expansion valves, float valves, or as a general purpose pilot line for ammonia, R22, R134a, CO2 and other approved refrigerants or oil.

HS8A 13mm solenoid valve

HA01308_

Introduction
This heavy-duty HS8A refrigeration solenoid valve is flanged, compact, and pilot-operated. It is now more dirt resistant, erosion resistant, and corrosion resistant than other similar refrigerant valves. A dirt controlling Teflon piston seal helps prevent sticking. The valve body has improved, erosion resistant flow
passages. A proprietary coating on the valve body gives unmatched corrosion protection. The HS8A is used to provide on-off control of refrigerant flow. When the coil is energized, a pressure difference across the piston opens the valve seat. When the coil is de-energized, a spring closes the main Teflon seat to stop all flow.

Applications
The HS8A is ideal as a liquid line solenoid valve. While primarily for ammonia, this valve is also suitable for R22, R134a, CO2 and other compatible refrigerants. The most common use of this valve is to control flow
to: expansion devices, recirculating liquid overfeed evaporators, hot gas defrost, and small capacity evaporator suction. In addition, the HS8A makes an ideal noncondensible gas (air) purge point solenoid
valve, and is recommended for use with Hansen AUTO-PURGERs.

HS7 20,25 & 32mm Solenoid Valve

HA0__07_

Introduction
This flanged, heavy duty, pilot-operated, industrial refrigeration solenoid valve controls the flow of refrigerant. When electrically energized, a slight pressure dif ference across the valve causes it to open
wide; when de-energized, a spring promptly closes the main Teflon seat to stop al l flow in the arrow direction on the valve body.

Applications
This advanced design valve is ideal as a standard, stock, ammonia liquid line solenoid valve. While primarily for ammonia, this valve is also suitable for R22, R134a, CO2 and other approved refrigerants. Most common use is to automatically stop liquid line feed to recirculating liquid overfeed evaporators, to float switch controlled accumulators, and to thermal expansion valves; it is also suitable for hot gas defrost, and evaporator suction. (Note: for gravity liquid drain or equalization applications use low pressure drop HCK2 gas-powered suction stop valve or HS9B gas-powered solenoid valve.)

HS4A 20-150mm Solenoid Valve

HA___140

Introduction
These advanced design, strong bodied, precision-manufactured solenoid valves control the on-off flow of refrigerant. They are superior in their ability to overcome dirt and sticky oil during opening and closing, and operate smoothly even in an oil-free "dry" system. When electrically energized, the upstream pressure is ported through the pilot solenoid to the top of the piston to push it downward and open the
main valve seat wide; when de-energized, pressure is no longer ported to the top of the piston and a spring closes the main valve seat to stop flow in the arrow direction on the valve body.

Applications
These reliable, flanged bodied valves are ideal for use as standard, stock refrigerant solenoid valves. While primarily for ammonia, these valves are also suitable for R22, R134a, CO2 and other approved refrigerants and warm refrigeration oil. Most common use is to automatically stop liquid feed to recirculating liquid overfeed evaporators, and as liquid makeup solenoid valve for pump recirculators. They are also suitable for hot gas defrost supply and evaporator suction stop applications. (Note: For gravity liquid drain or equalization applications, use low pressure drop Hansen Type HCK2 gas-powered suction stop valves or Type HS9B gas-powered solenoid valves.)
