DEMA’s pilot-piston valves are available for 3/8-1” pipes, have multiple orifice sizes from 9/32 to 3/4”, have brass bodies, stainless steel seats and Teflon seals. With pilot-piston valves, the stem and plunger assembly opens the port. This releases the pressure on top of the piston, which moves upward and opens the main valve port.
