Dema manufactures solenoid valves such as high pressure valves, line strainers, manifold valves, normally closed valves and normally open valves. High pressure solenoid valves are normally closed brass valves with a 1200 psi maximum operating pressure, stainless steel sleeves and seats, and sizes of 3/8", 1/2" and 1" NPT. Their line of manifold valves includes normally closed brass manifold valves in 1, 2, 3, 4 or 5 stations in Model 492M2M and 492M2. Normally closed solenoid valves are offered in various models with a variety of voltages, body materials and maximum operating pressures. Normally open valves includes normally open brass diaphragm valves in 3/8", 1/2" and 3/4" NPT, as well as normally open high pressure piston valves rated up to 1000 psi with 3/8" NPT connection.
