Description:
The externally piloted angle-seat valve is operated with a single or double-acting piston actuator. The actuator is available in two different materials, PA and PPS depending on the ambient temperature. The reliable self-adjusting packing gland provides high sealing integrity. High flow rates are attained with the gunmetal or cast stainless steel 2-way body. These maintenance-free and robust valves can be retrofitted with a comprehensive range of accessories for position indication, stroke limitation or manual override.
2/2-way Angle-Seat Valve for medium up to +180°C, threaded port connection, DN 13-65
* High flow rate
* Long life cycle
* NC and NO universal actuators with modular universal accessory program up to control heads
* Deliverable with flow direction below or above seat
* Simple conversion of the control function
