DMF-Z Threaded Pulse Valve

The inclined angle between air inlet and air outlet is 90°. The inlet and outlet are threaded ports. They are suitable for connecting air tank with blow pipe for bag filters with smooth air flow and they can provide efficient dust-cleaning.

Product Description

The DMF-Z Series is a range of diaphragm pulse valves suitable for dust collector applications, in particular for reverse pulse-jet filter cleaning of filter bags, cartridges, envelope filters, ceramic filters and sintered metal fiber filters. The DMF-Z Series valve has the inlet port at 90° to the outlet port. The DMF-Z Series range comprises 7 models, from ¾″ to 2½″, all with threaded female Gas connections. The ¾″ and 1″ model is in single diaphragm design, while the 1½″, 2″ , 2½″ , 3″ and 4″ are all double diaphragm valves. The special design assures an extremely fast opening time, high flow rates and easy installation. The valves are constructed in die-casting aluminium and have an anodised protection treatment which protect them from corrosive and environmental agents. Bolts and screws are in stainless steel.

Structure & Working Principle

Made of die-cast aluminum alloy, the valve is equipped with a durable rubber diaphragm and fully encapsulated solenoid coil with IP65 protection. When no electric signal is applied, compressed air keeps the diaphragm sealed, and the valve stays closed. Once receiving an electric pulse signal, the pilot mechanism releases air pressure instantly, the diaphragm lifts, and high-pressure air sprays out to clean filter bags. After the signal disappears, the valve automatically resets and closes.

Precautions before installation of right-angle pulse valve

▼ Clean the interior of the air tank and pipeline to prevent dirt from blocking the damping or exhaust holes;
▼ Check whether the thread size of the blowpipe matches the thread size of the valve installation port; the thread size should be standard pipe thread.
▼ Ensure that the power supply has been cut off and there is no internal pressure in the gas bag;
▼ Pay attention to the direction of the inlet and outlet of the right-angle electromagnetic pulse valve before installation;
