UNIJET Non-Return valve opens on a very low cracking pressure and closes at a low differential even at high pressure. The Non returnvalves feature a large, resilient poppet that provides soft-seat sealing for bubble tight closure, even under low pressure conditions. Gunmetal construction plus a choice of seal materials provide excellent compatibility with wide range of air media. The valve is efficient in operation while handling gases and liquids under pressure. Unijet check valves are perfect for applications requiring high pressures (up to 230 PSI standard).
The valve is self-aligning unit and hence can be mounted in any position. For easy service or repair, removal of hex nut from body gives quick access to valve’s poppet assembly without the need to disconnect piping.
