ball and needle valvesBifold was established over a century ago, manufacturing a range of steam VALVES and equipment for the coal mining industry.

The Bifold Group has re-developed its range of ball and needle valve products and re-launched the range for low/medium pressure applications with operating range from 1,000 psi / 70 bar up to 15,000 psi /1035 bar. The valves offer exceptional integrity to meet medium pressure and other demanding instrumentation applications that are increasingly being faced in the upstream and downstream oil and gas sector.

Constructed from 316 stainless steel as standard (other material options offered), in compliance with NACE MR-01-75 as standard and with 1/4" up to 2" tube connection sizes.

The Ball Valve range utilises a state of the art design to reduce potential leak paths. They are bi-directional and are actuated by a 90 degree turn handle as standard, for fast on/off action. The valve mechanism works on the floating ball principle and offers 100% bubble tight operation. The use of PEEK seat and stem seal materials allows operation over a wide temperature range from -20
