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)
