The externally piloted diaphragm valve consists of a pneumatically operated piston actuator, a diaphragm and a 2-way valve housing made of investment cast stainless steel.
The standard material of the actuator is PPS. With its favourable fl ow characteristics and zero dead volume, the valve housing enables high flow capacities and a variety of applica-tions to be realized.
