Dwyer SSV-B4N1 is a brass solenoid valve designed for 2-way guided no process applications. It can handle temperatures up to 176°F (80°C) and has an ambient temperature range of 32 to 149°F (0 to 65°C). The valve operates on a standard 110 VAC power requirement, with optional 220 VAC or 24 VDC configurations available. It has a NEMA 13 (IP54) enclosure rating and features a DIN electrical connection. The valve is compatible with gases and liquids and has a maximum pressure limit of 174 psi (12 bar). It has a female NPT process connection and is constructed with a brass body, 304 SS spring, and NBR seal. The valve can be mounted in any position, but it is best to have the solenoid vertically above the valve. The wetted material is nylon and it is available in line sizes ranging from 1/8 to 2" NPT. The maximum operating pressure varies depending on the size of the valve, with 1/8 to 1/4" valves having a range of 0 psi (0 bar) to 87 psi (6 bar), and 3/8 to 2" valves having a range of 7.3 psi (0.5 bar) to 116 psi (8 bar). The valve operates as a normally open (NO) configuration.
