SERIES 756 DOUBLE ECCENTRIC INTEGRAL SEAT BUTTERFLY VALVE, PN16
The range of Series 756 butterfly valves conform to BS EN 593 for regulating or isolating flows in pipelines up to DN2200. 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.

Features

• Double eccentric disc reduces seal wear and torque requirement.
• Flat profile disc reduces head-loss across the valve.
• Disc/shaft interface keyed and pinned.
• European “long” body pattern to DIN 3230 pt 4.
• Fusion bonded epoxy coated.
• 2 Mounting feet and ISO mounting flanges to optimize installation options.
• Lifting points.
• All materials WRAS approved.

Options

• Gearbox for buried service.
• Gearbox for above ground duty.
• Handwheel.
• Electric actuation.
• Trim option available PN25 (not all sizes).
• Alternative flange drillings.
* NB. Should always be used when valve is orientated vertically.
# It is a requirement of the HSE Machinery Directive that guards are fitted to cover Levers & Weights when utilised.
