The externally controlled angled seat valve consists of a pneumatically operated piston actuator and a 2-way valve body. Depending on the ambient temperature, the actuator is available in two different materials, PA and PPS. The proven self-adjusting stuffing box ensures high tightness. The flow-optimized 2/2-way valve bodies made of stainless steel enable high flow values. These maintenance-free and robust valves can be retrofitted with a comprehensive range of accessories for position indicator, stroke limitation or manual emergency operation.
