Line mounted poppet type check valve with adjustable cracking pressure. Flow is always allowed to pass from port A to port B when pressure at A rises above the spring bias pressure and the poppet is pushed from the seat.
The spring load is adjustable by turning the internal ring nut with a insex wrench: screwing down increases the spring load and increases the cracking pressure (in order to turn the Ring Nut, loosen first the little locking screw with a insex wrench; tighten it again once the spring load is adjusted).
The valve is normally closed (checked) from B to A.
