Direct Acting Valves

DEMA’s direct acting valves are available for 1/8-1/4” pipes, have orifices of 7/64, 1/8 or 3/32”, have brass or stainless steel bodies and Buna N, Viton or EPDM seals. With direct acting valves, the stem and plunger assembly opens the port of the valve directly and requires no minimum pressure to operate.
