Ball Valves

We stock several classes of low cost, reliable Waverley Brownall ball valves, machined from high grade 316 stainless steel. Each valve can withstand working pressures of between 1,000 & 10,000 psi.

  • Standard sizes range from 6mm to 25mm
  • Single or twin ferrule varieties
  • Single piece reduced bore, or two to three piece full bore types
  • NPT, BSPT and BSPP thread forms

Needle Valves

Our range of needle valves and manifolds are designed to withstand extreme operating pressures of up to 10,000 psi and temperatures of up to 4,000°C. The valves are manufactured from durable 316 stainless steel and incorporate a split stem with non-rotating ball tip. This ensures a tight bubble seal for accurate seating.

  • Wide range of end connections available from 6mm to 12mm diameter (OD)
  • Male or female connections
  • NPT or BSP thread
  • Available as two-way, three-way or five-way valves

Monoflange Valves

Monoflange valves are a great alternative to multivalve systems, providing isolation, instrument mounting and venting within a single, compact unit. The design incorporates an outside screw and yoke for the primary isolation valve.

Monoflanges can be ordered with a twin ferrule, 12mm OD end, or NPT female connection.

  • Inlet ports from 6mm to 25mm
  • NPT, BSPT and BSPP thread form available

2) The Mini Series check valve range are small, robust single piece components designed to give a unidirectional flow control of up to 6,000 psi. These valves have adjustable springs that let you set a range of cracking pressures. The Mini Series is available with 6mm or 12mm NPT male connections.
