BÜRKERT's compact and economical Type 5281 waterhammer-free diaphragm solenoid valve combines a rugged reliability with high flow characteristics, making it ideal for water and inert media flows.
Rapid valve response is a key feature of the 5281, with 0.2 - 0.5 sec opening and 1.0 - 4.0 sec closing offering high operational accuracy and control. Low noise, the 2/2 way normally closed 5281 solenoid valve is a powerful unit known for its long life cycle and minimal maintenance needs.
The valve operates with 0.2 to 16 bar pressure and media temperatures -10ºC to +90ºC with the standard NBR seal (-30ºC to 130ºC EPDM seal; -10ºC to +130ºC FPM seal).
Flexible power supply options are standard, including ac 24V, 110V, 230V/50-60Hz and 24V dc with 10% tolerance. The valve is continuously rated, with 100% duty cycle.
Engineered and manufactured in Germany as a completely modular valve concept, the 5281 combines three basic elements: valve assembly, push-over coil and standard cable plug.
Matching specific flow, media and environmental conditions, Bürkert's modular concept allows an easy and economical 5281 valve build specific to your particular process needs.
The valve body is available in brass with a wide selection of pipe and orifice sizes from 1/2 to 2-1/2 inches, with threaded ports. The diaphragm, plunger-seal and O-rings are offered in NBR (standard), EPDM or FPM.
The solenoid coil is pushed over the armature guide tube, and isolated from the media flow. The coil is designed to lock in four 90º positions or moved freely between as required, and is easily replaced. Available with optional manual override, the 5281 is also available in low power 2W and 5W consumption models.
Cable plugs are rated IP65, DIN 43 650A, 0-250V as standard, with other versions available.
