Pentair Keystone OS1700 high-pressure, zero-leakage knife gate valve

Friday, 04 March, 2016 | Supplied by: Pentair Valves & Controls

Pentair Valves & Controls has launched the Keystone OS1700 — a bidirectional, zero-leakage ASME Class 150-rated knife gate valve designed to provide users in sectors from mining to pulp and paper with good performance at higher pressures.

The product has a full-round port and seat design that places the elastomer seat outside the flow path, minimising turbulence to extend the life of the valve and protect downstream pipework and equipment. It is suitable for inline or dead-end service up to full rated pressure.

Built to MSS-SP135 short pattern specifications, the valve is said to require less maintenance than other styles of knife gate valves. The MSS-SP135 short pattern face to face matches MSS-SP81 dimensions, so upgrading an existing knife gate installation is simple.

The product is suitable for challenging applications such as high-pressure slurry and oil sands applications. It also suits users looking for a product to protect against process pressure spikes that could damage an ordinary knife gate valve and any associated equipment.

It is available in sizes from NPS 2 to 48 (DN 50 to 1200). The precision-moulded elastomer seat — which is available in EPDM, HNBR or GUM — enables the valve to operate at up to 200°C.
