Product Name: JR-CK-15 Butterfly Swing Check Valve with counterweight and cylinder
 
   SPECIFICATION/SPECIAL FEATURES
The butterfly check valves with oil cylinder are very reliable as they can regulate the closing time of the valve. These valves are applied in pipelines as non-return device, with flow allowed in one direction only. The oil cylinder will slow down the closure movement, to reduce any slam with noise. Epoxy coated inside and outside, the double flanged butterfly valves can be installed in drinking water plants. NBR gasket seals are on the disc and can be replaced without dismantling the valves from the pipeline.
