NPT/SAE Safety Valve
A compact straight safety valve that combines a threaded NPT inlet with a 45° SAE flare outlet, giving service teams a metal-to-metal flare joint that can be disconnected without cutting or brazing. Four models span DN8-DN15 with inlets from 1/4" to 1/2" NPT. Like the rest of the FS range, each valve is spring direct-loaded, factory set and lead-sealed, with five standard set pressures from 2.0 to 3.4 MPa.

Standard Solenoid Valve — Piston, NC, Brazed ODF (HVD Series)
The standard mainstay refrigeration solenoid valve in this range, the HVD Series features a piston structure and pure ODF brazed connection for reliable high-pressure operation. With 8 models covering port sizes from 3/8" to 1-5/8", it serves a wide range of HCFC and HFC refrigeration and air conditioning systems.

High Flow Solenoid Valve — Piston, NC, Flanged ODF (HVP Series)
Delivering the highest flow capacity among standard refrigeration solenoid valves, the HVP Series features a flanged-edge valve body designed for large-diameter refrigeration applications. With 4 models covering ports from 1-1/8" to 2-1/8" and Kv values up to 28 m³/h, it is ideal for industrial and commercial refrigeration systems requiring high-capacity refrigerant flow.

Clamping Type Solenoid Valve — Small Port, Diaphragm, NC (HV Series)
A compact diaphragm solenoid valve with a clamping coil design that allows tool-free coil removal for quick maintenance, the HV Series (Small Port) covers port sizes from 1/4" to 3/8" and offers the widest voltage range in the lineup (AC380V/220V/110V/24V, DC12V). It is ideal for compact refrigeration and air conditioning installations.

Clamping Type Solenoid Valve — Large Port, Diaphragm, NC (HV Series)
The large-port variant of the clamping-type solenoid valve, covering port sizes from 1/2" to 1-1/8" with Kv values up to 4.5 m³/h. Shares the same tool-free clamping coil design as the small-port version, making it ideal for medium-capacity refrigeration and air conditioning systems.

IP65 Direct-Acting Solenoid Valve — Diaphragm, NC (SV Series)
A compact direct-acting solenoid valve with IP65 protection rating, the SV Series (Direct) covers port sizes from 1/4" to 3/8". Its direct-acting design ensures reliable operation even at zero pressure differential, making it suitable for small-capacity refrigeration systems.

IP65 Servo-Operated Solenoid Valve — Diaphragm, NC (SV Series)
The servo-operated variant of the IP65 solenoid valve, covering larger port sizes from 1/2" to 1-1/8" with Kv values up to 4.5 m³/h. Ideal for medium-capacity refrigeration systems requiring higher flow rates.
