T-T Flow Supplies Custom DN600 metal seat gate valves to Portsmouth Water

While refurbishing Farlington Water Treatment Works at Portsmouth Water, the contractor needed a smart solution to transition from an old imperial legacy pipework to new metric pipework, whilst maintaining the ability to isolate the flow.  T-T Flow stepped in when the appointed framework valve holder was inflexible to accommodate the challenge.

T-T Flow chose to supply eight 600mm metal seated isolating wedge gate valve rated to 16 Bar having custom flange drillings, one side metric (EN1092 PN16) and the other side imperial (BS10 Table D).

The eight DN600 PN16 metal seat wedge gate valve conformed to BS5163 and were hydraulically tested to EN12266. The full-bore valve feature precision machined weld-overlay leaded gunmetal seating faces able to withstand higher flow velocities, non-rising stainless steel rolled threads for reduced friction, thrust taking bonnet assembly and manufactured from ductile iron coated in a durable WRAS listed fusion bonded epoxy coating.  Wedge gate valves lend themselves to wide ranging flow isolating duties for medias such as; potable water, raw water, wastewater and low solid content sewage.

T-T Flow offer metal seat and WRAS approved resilient gate valves from DN50 to DN1200 rated to 16 Bar, larger diameters and pressures are also catered for.  To compliment the gate valve range, we also stock WRAS approved swing check valves. 

A full range of accessories including tapered stem caps, handwheels, reduction gearboxes (bevel and spur), electric actuators and custom operating equipment such as extension spindles are available.
