Bürkert Pneumatically Operated 2/2-WAY Angle Seat Valve CLASSIC

The externally controlled angle seat valve consists of a pneumatically operated piston actuator and a 2-way valve body. The actuator is available in two different materials, PA or PPS, depending on the ambient temperature. The proven, self-adjusting packing gland guarantees a high degree of tightness. The flow-optimised 2/2-way valve bodies from red brass or stainless steel investment casting enable high volume flow rates. These maintenance-free and robust valves can be retrofitted with a comprehensive range of accessories for position indication, stroke limitation or manual override.
