Aquaflow has introduced a range of full-bore metal seat wedge gate valves into its valve portfolio, available from T-T Pumps.

The valves, available from DN80 to DN300, meet BS5163:2004 and are suitable for either isolated or buried duty.

They withstand a maximum working pressure of 25.0 bar and shell tested to 37.5 bar according to EN12266:2003.

The range has a ductile iron, fusion-bonded epoxy coated (WRAS listed) body, gunmetal seat rings, clockwise-closing stainless steel non-rising spindle, replaceable triple O-ring seals and undrilled body bosses.

The standard operation for this range is by either a handwheel or stem cap; however, an ISO5210 pad can be fitted for safe, cost-effective mounting of actuators or gearboxes.

Flange connections are to EN1092-2:2002 Table 10, with face-to-face dimensions according to EN558-1:1986 Series 3.

The face-to-face dimension of this range is the same as the PN16 version; therefore it accommodates less room than traditional PN25 gate valves with the longer face-to-face dimension.

This new range has a number of associated accessories available for purchase, including: extension spindle; T-key; position indicator; locking device; chainwheel; ISO5210 mounting pad; actuator; and bevel/spur gearboxes.
