FABRICATED SINGLE WEDGE VALVE

FABRICATED SINGLE WEDGE VALVE

Single wedge knife valves manufactured on request. Unidirectional or bidirectional closing. Ideal for installations requiring high levels of watertightness or high working pressures or which handle hazardous fluids.

The main features of the valve:

• Construction body and bonnet: provides total watertightness both in the seat and towards the outside.
• Gate with rounded edges: prolongs the working life of the rings.
• Designed for demanding work load, and pressures.
• Upper bonneted design provides excellent sealing.
• Easy maintenance.
• The Packing o’ring and packing can be replaced easily from outside (It is not necessary to disassemble the valve)

* Valves manufactured following European Pressure Equipment Directive PED 2014/68/EU.
