Hansen Solenoid Valves are designed and built specifically for industrial refrigeration. These high-quality valves are compact, strong-bodied, and reliable. Stainless steel pistons or disc-pistons with Teflon seals are used to overcome the problem of valve sticking due to dirt or lack of oil. Pilot seats are polished stainless steel on Teflon discs and main valve seats and discs align for tight closing. Each valve is tested on a sensitive leak detection system to ensure reliable operation, safety, and tightness.
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.
Hansen Technologies introduces the HS4D Two Step Solenoid Valve. The HS4D is based on the same strength, reliability, design principles and craftsmanship as the standard Hansen HS4A Solenoid Valve—with added versatility.
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.
This flanged, heavy duty, pilot-operated, industrial refrigeration solenoid valve controls the flow of refrigerant. When electrically energized, a slight pressure difference across the valve causes it to open wide; when de-energized, a spring promptly closes the main Teflon seat to stop all flow in the arrow direction on the valve body.
his 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.
