They have a temperature range of 32 to 176°F and come with a 110 VAC power requirement (optional: 220 VAC, 24 VDC, 24 VAC). The valves have an enclosure rating of NEMA 13 and electrical connections with DIN connection. They can be mounted in any position, but it is recommended to have the solenoid vertically above the valve. The wetted material includes a brass body, 304 SS spring, and NBR seal. The maximum operating pressure ranges from 0 psi to 188.5 psi depending on the line size. The valves have a female NPT process connection and are made of nylon material.
