Areas of application
The conveying diverter valve TYPE SRW is a two-way diverter valve for application in pneumatic high- and low-pressure conveyor systems. Suitable for conveying of dry, non-caking bulk goods from powdery up to abrasive. Because of variable sealing materials, bulk goods with temperatures up to 180° C can be conveyed without problems. The material cushion accumulation during dense stream conveying transfers the wear zone into the material cushion away from the valve walls.

Operation
A shifting swivel arm distributes the bulk goods. The swivel arm is equipped with a gasket cone with easily exchangeable gaskets. Sealing is effected against hardened interior rings. Shifting is achieved via a pneumatic or electro-motoric swivel drive. Swivel drive with limit switches for position indication.
Pneumatic swivel drive with 5/2-way impulse magnetic valve guarantees secure operation - even during power outage.
