2/2-way Angle-Seat Valve, compact valve body, for media up to +180 °C, DN13-65 ? Ultra compact version, short face-to-face length ? Long service life ? Valve body in gunmetal

and stainless steel ? Deliverable with ?ow direction below or above seat

Type 2002 can be combined with...

Type 6012/6014 P Pilot valve

Type 8631 TopControl On/Off

Type 8640/8644 Valve block

Type 5470 Solenoid valve

Type 6519 NAMUR

The pneumatically operated 2/2-way valve is operated with a piston actuator. The actuator is available in two different materials, depending on the ambient temperature. The standard material is PA for high ambient temperatures (e.g. external sterilization) PPS is available for temperatures up to 140?C.High ?ow rates are attained with the gunmetal or stainless steel 2-way body with a short face-to-face length. Compatible with the Type 0251. The reliable self-adjusting packing gland provides high sealing integrity. These maintenance-free and robust valves can be retro?tted with a comprehensive range of accessories for position indication, stroke limitation or manual override.
