We manufacture a variety of valve stems in a wide range of sizes.
Gate stems and globe stems, which mainly have an ACME thread, are used in valves for oxygen, acids, sea water etc., and are a particular area of expertise for us. They are also the main type of valve stem that we produce.
Gate stems and globe stems are manufactured from materials such as aluminium-bronze, stainless steel, nickel-based alloys, duplex, super duplex, Inconel alloys, Monel alloys, titanium etc.
Our size range spans from as small as 12mm diameter by up to 3 metres in length. All of our valve stems are finish turned using a CNC lathe, to a tolerance of + / - 0.02mm with a surface finish of 0.4 to 0.8.
