SERIES S756 DOUBLE ECCENTRIC INTEGRAL SEAT BUTTERFLY VALVE, PN25
The range of Series 756 butterfly valves conform to BS EN 593 for isolating flows in pipelines DN800, DN1000 - DN1400. Manufactured from ductile iron, valves incorporate a positive retained resilient disc seal and either an integral or replaceable body seat. The valve has three unique attributes: less weight, more strength and lower torque. The integral seat design is for use on water treatment and water distribution lines where buried service is required.
