RFT is a highly experienced and innovative engineering company. We specialise in producing fully finished valves.
Our products are machined, assembled, tested and certified entirely in the UK and meet all required industry standards.
RFT work in close conjunction with our parent company Drysdale Brothers, a Lloyds approved foundry, to produce top quality castings. Utilising MagmaSoft simulation software to optimise the casting process ensures a high integrity product from the offset.
To ensure the pressure integrity of our valves, RFT has state-of-the-art seat lapping machines for valve bodies and lapping tables for valve plates. This ensures the best possible quality and flatness for the lapped surfaces on all our metal-seated valves.
In accordance with ISO 9001 all Incoming goods are subject to full inspection to ensure compliance with drawings and standards. Chemical analysis is verified using our NITON XRF - PMI Analyser.
We test 100% of our finished products to international standards. All tests are documented and certified. We have recently purchased a Ventil pressure-testing station, allowing us to test hydrostatically up to ANSI 2500lb, as well as undertake low-pressure air and gas-seat testing to API 598.
RFT has invsted in the latest Laser etching technology for Identifying our products. Laser etching is permanent, tamper proof and resistant to damage from chemicals and abrasion.
To develop Valves that meet all our customers’ needs, RFT has its own on-site design and engineering department. We use state-of-the-art 3D modelling to develop all our products, no matter the size and pressure class.
Standards & Materials
Our 'retainer-less' dual-plate check valves are manufactured in accordance with API 594, ASME B16:34 and tested to API 598. We stock a comprehensive range of valves up to the 600lb pressure class in ASTM A 352 LCC low-temp carbon steel, ASTM A 351 CF8M stainless steel and C95800 aluminium bronze body materials.
Other exotic materials and pressure classes for specialised applications are available by request. Stock metal seated valves can be modified with soft seating materials: EPDM, NBR and VITON. They're also available with Stellite 6 hard facing on the seat upon request.
Our stock range of products can be modified to suit most international flange standards.
