Dwyer SSV-B8N4 is a brass solenoid valve designed for 2-way guided flow control. It can withstand temperatures up to 176°F (80°C) in process conditions and operates at ambient temperatures ranging from 32 to 149°F (0 to 65°C). It requires a power supply of 110 VAC as standard, with optional 220 VAC and 24 VDC available. The valve has a NEMA 13 (IP54) enclosure rating and comes with DIN electrical connections. It is suitable for use with compatible gases and liquids. The valve consumes power based on the specifications outlined in the catalog. It can be mounted in any orientation but is most effective when the solenoid is positioned vertically above the valve. The wetted materials of the valve include a brass body, 304 stainless steel spring, and NBR seal. It has a pressure limit of 174 psi (12 bar) and features a female NPT process connection. The valve is made from nylon material and is available in line sizes ranging from 1/8 to 2" NPT. The maximum operating pressure varies depending on the line size, with 1/8 to 1/4" allowing for pressures from 0 psi (0 bar) to 87 psi (6 bar), and 3/8 to 2" allowing for pressures from 7.3 psi (0.5 bar) to 116 psi (8 bar). It operates as a normally open (NO) valve.
