Instrument ball valves to 10, 000psi (floating ball) Instrument ball valves to 15, 000psi (trunnion mount) Instrument 3-way ball valves to 10, 000psi (floating ball) Instrument manifolds, gauge, 2 and 3 valve manifolds to 3, 000psi Actuated ball valves NACE, firesafe and anti-static service options Connections may be threaded, flanged, butt weld or socket weld ends 'Barstock' range of Double Block & Bleed valves Key Features Our ball valves have very low operating torques and a range of seat materials to give the ultimate in process environmental compatibility Our seats offer wide process compatibility whilst maintaining a positive sealing across the entire operating range. This high level of seat integrity allows both vacuum and high pressure services from one valve All valves are available in firesafe configuration ensuring when closed valves maintain leak free status across ball and up spindle A one piece stem incorporates an anti-blow-out shoulder which maintains seal integrity at all pressures With the three piece ball valve the tangential locking pin option ensures total elimination of the possibility of removal of the end connectors (patented) Ball valve manual actuation is by a 316 stainless steel handle as standard, other operations for actuation are handle locking, spanner actuated, oval handle or in conjunction with panel mounting a range of 'PMB Series' coloured handle's Technical Specification 10mm, 14mm and 20mm bores in 1/4" to 1" threaded connections and pressures to 6, 000psi - consult factory for more information Connections female x female, male x female, compression fitting, butt weld and socket weld available Option of fire tested in accordance to BS 6755 Part 2 and API 607 All Oliver ball valves are subjected to three pressure tests; a hydrostatic test at 1.1 standard working pressure; low pressure pneumatic test at 87psi (6 bar); as well as a Shell test to 1.5 times working pressure Valves can also be supplied as an option to NACE MR-01-75 (latest revision) suitable for sour service
