- Stainless steel or brass body with threaded connection High service live Compact design Variant for steam applications available The externally piloted 2-way valve is operated by a diaphragm actuator. A double spindle seal guarantees high tightness and a high service live. The compact actuator housing is made out of chemical resistant plastic and ideal for customer specific multifunction block solutions. This low maintenance and robust valve can be supplemented by a large accessory program. Product variants described in the data sheet may differ from the product presentation and description.
