PNEUMATIC CONVEYING DIVERTER VALVE(MDV)
To divert a conveyed material stream into two pipelines in high - or low - pressure conveying systems
MDV VALVE Areas of application
The conveying diverter valve TYPE MDV 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.Material/design Housing: grey, nodular-cast iron or stainless steel casting Swivel arm: nodular- or stainless steel-cast iron Sealing ring: rubber, silicone, viton Painting: hammertone, silver-grey
Technical data Pneumatic swivel drive:
Operating pressure: 7 bar Control pressure: 5 bar Limit switch box with mechanical limit switches, Solenoid valve voltage: 24 V DC/24 V AC/ 230 V AC As control valve a 5/2-way impulse magnetic valve is used. Pneumatic actuator swivel drive: Operating pressure: 10 bar Voltage: 24 V/AC or 24v/dc Limit switch box with mechanical limit switches, made by Schmersal Hand-drive: with hand swivel lever
Operating pressure: 7 bar Advantages
· Material cushion formation during dense stream conveying
· Wear zone diverted into the material cushion
· During power outage the swivel arm remains in the selected position
· Sealing rings can be exchanged without disassembly during shortest stoppages
· Pressure tight, even in the low pressure area
