For a number of years, Parker has offered a range of double block and bleed Process to Instrument valves in 5000 psi and 10,000 psi maximum rated working pressures. The needle valve version is already available in all three pressure ratings (5000, 10,000 and 15,000 psi), but the ball valve version has only been available in 5000 and 10,000 psi until now. Due to customer demand for higher pressure straight-through bore, Parker has introduced a 15,000 psi fire-safe version to complete the range in both configurations.
Parker sourced a new packing material and modified head assembly to ensure great results and successful PR2 and PSL3 testing was achieved.
Jim Breeze, product manager at Parker – Instrumentation Product Division Europe, explains: “We have responded to demand in the market for a higher pressure 15,000 psi double block and bleed valve, which enables us to meet all customer requirements for this type of valve.”
Parker's valves are lightweight and compact, which is essential for offshore installations. They can easily be installed to existing designs and offer low cost fabrication.
Parker’s valves are also suitable for HIPPS (high integrity pressure protection systems) for use in wellhead flowline pressure protection.
All Parker’s double block and bleed valves have been tested for conformance to API 6A specifications by an independent test house, as well as by the internal test laboratory that Parker operates at its European design and manufacturing facility in Barnstaple, UK. The valves are Saudi Aramco-approved and comply with the 9-com material classification system.
