Oliver Valves Product Categories

We stock Oliver Valves products designed for small-bore isolation, instrumentation, and process-control applications.

Oliver Needle Valves

The Oliver needle valve is built around a non-rotating, anti-galling spindle tip, a dynamic self-adjusting piston-ring seal, and an anti-blowout spindle. The range covers single-isolate hand valves, miniature needle valves (MFF type, 1/4" NPT or 1/2" NPT female), heavy-duty variants, and high-pressure builds. Standard rating is 6,000 PSI at 240 °C with PTFE packing, uprateable to 10,000 PSI (/HP), 15,000 PSI with autoclave fitting (/15HP), and 22,500 PSI (/22.5HP). Cryogenic variants (/LT200) run down to –200 °C. Standard body material is 316 stainless steel; options include carbon steel (230M07), Monel 400, Hastelloy C-276, Duplex (UNS S31803), and Inconel 625. Firesafe builds are certified to BS 6755 Part 2, API 607, and API 6FA.

Oliver Instrumentation Valves

Oliver instrumentation valves are designed for primary isolation and gauge protection on process and analyser lines. The range covers root valves for primary isolation in single block, block-and-bleed, and DBB configurations (welded, screwed, or flanged) slimline primary isolate valves that combine the primary isolation valve with the instrument block-and-bleed; gauge syphons (SY50S, 316 SS, 6,000 PSI) to protect gauges from steam; gauge snubbers (SN50S, variable orifice, 6,000 PSI) to dampen line surges; and swivel gauge adaptors (GA50S, 6,000 PSI to 540 °C) for 360° gauge positioning on site. Built in 316 stainless steel as standard, with NACE MR-01-75 sour-service variants on request.

Oliver Manifold Valves

Oliver manifolds are supplied for gauge and differential pressure transmitter mounting in two-valve (G12AF, Y24, Y25), three-valve (Y35, T34, H33), and five-valve (Y52, Y53, Y54) configurations. Variants cover direct mount (pipe-to-flange and flange-to-flange) and remote mount (pipe-to-pipe). Standard rating is 6,000 PSI at 240 °C with PTFE packing (uprateable to 10,000 PSI with /HP); manifolds with stainless steel bolts are rated to 4,800 PSI (or 6,000 PSI with /SSB-6K high-tensile bolt option).

Oliver Monoflange Valves

Gauge Block Monoflange Valves combine block-and-bleed isolation with a flange-direct gauge connection, eliminating intermediate piping and reducing leak paths, installation weight, and overall footprint at the instrument tie-in. They are supplied with primary and secondary isolation and an integrated vent, with Tee-Bar or Hand Wheel operation. Slimline Monoflange variants offer a further compact envelope for gauges and transmitters at the pipeline tap. Process connections are ANSI flanged with NPT or BSP instrument-side ports. Standard body materials are 316 stainless steel and carbon steel, with speciality alloys on request. NACE MR-01-75 sour-service variants are supplied as a factory option, with firesafe certification to BS 6755 Pt 2, API 607, and API 6FA.

Oliver Check Valves

Oliver in-line poppet check valves (CV Type) allow flow in one direction only and close automatically when flow reverses. Sizes cover 1/4", 3/8", 1/2", 3/4", and 1" NPT female x female, all in 316 stainless steel with 316 stainless steel springs. Standard rating is 6,000 PSI for all sizes; the 1/4", 3/8", and 1/2" sizes can be uprated to 10,000 PSI with the /HP option. Maximum operating temperature is 120 °C. Seats are Viton as standard, with Viton 90 (NACE), Kalrez, and PEEK on request (PEEK is required for hydraulic service). Minimum cracking pressure is 7 PSI.

Oliver Injection & Sampling Valves

Oliver sampling DBB valves take process samples at full line pressure with double isolation, while injection DBB valves use a one-way inlet check valve that opens for chemical injection and closes to prevent backflow. Bodies are single-billet forged to ANSI B16.5 dimensions with two isolating valves and a bleed needle valve, probe lengths up to 24" in 316 stainless steel as standard. Check valve seats are Viton standard, with Kalrez for methanol service. NACE MR-01-75 sour-service and oxygen-clean variants are available.

Oliver Gauge Valves

Oliver gauge valves are needle-pattern valves designed for direct mounting on pressure gauges and transmitters, using the same non-rotating tip, anti-blowout spindle, and self-adjusting piston-ring seal as the standard hand valves. Standard rating is 6,000 PSI at 240 °C, uprateable to 10,000 PSI with /HP. Panel-mount (PM) versions with 4× M5 mounting holes are available, as are NACE MR-01-75 sour-service variants. Standard material is 316 stainless steel.
