Pentair Keystone OS1700 bidirectional knife gate valve
Pentair Valves & Controls has launched the Keystone OS1700, a bidirectional, zero-leakage ASME Class 150 rated knife gate valve designed to provide high performance at high pressures for applications in sectors from mining to pulp and paper.
The full-round port and advanced seat design, which places the elastomer seat outside the flow path, minimises 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, it is said to require lower maintenance and offer improved reliability.
The product is designed for challenging applications, such as high-pressure slurry and oil sands applications, but it is also useful for protecting against process pressure spikes that could damage an ordinary knife gate valve and any associated equipment. The MSS-SP135 short pattern face to face also matches MSS-SP81 dimensions to make upgrading an existing knife gate installation simple.
The valve 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.
