La description

Pulse diaphragm valve, NC, 230 V, 50 - 60 Hz internal pre-control, Medium temp. max. 85 °C, G 1, PN 0.35 - 8.5 bar, TPE diaphragm. Environmental protection today demands state-of-the-art cleaning processes. Dust filter systems are an indispensable aid to pollution control.The fabric filters installed in these systems are cleaned by blowing in compressed air pulses in quick succession counter to the main direction of flow.The solenoid valves used for this purpose are characterised by the following application-specific design features:- Angle type of construction to optimise the air flow- Full cross-section at the valve seat- Extremely fast opening and closing- Quiet operation thanks to built-in silencers (can be retrofitted in sizes 1 1/2­ to 2 1/2)- Easy maintenance and repair because diaphragm and wearing parts are instantly availableThe valves are not suitable as shut-off devices for standard applications.
