Brass valves

Spartan Scientific introduces its Series 3505, a two-way, two-position, normally closed valve for the control of air, emulsion, inert gases and water. The valve features an all brass body and a zero-minimum pressure differential while still boasting a full flow 0.5-inch (12.7 mm) orifice. Available in 0.25-, 0.375- and 0.5-inch (6.35-, 9.52-mm) NPT, the valves can handle pressures to 230 psi. An encapsulated coil construction ensures the valve functions well under long periods of energization (100-percent duty), as well as providing a high degree of environmental protection (NEMA 4). The inner valve functions as a direct assist using a flat diaphragm and orifice plate. Pressure differentials shift the valve to full open or full closed. A push, non-locking manual override is standard. All valves are manufactured to high quality standards and are made in the USA.
