Gate Valves

Gate Valves are Bi-Directional and mainly used for On/Off operation with low pressure drop. A rising stem provides position indication. The solid or flexible wedge will seal against metal seats with acceptable leakage rates per API 598. When fully open, the typical gate valve has no obstruction in the flow path, resulting in very low friction loss.

Globe Valves

Globe Valves are Uni-Directional and are designed for regulation / control of flow, also known as throttling. Various disc designs are available. The standard is a Plug or Ball type but for varying control of regulation Needle, Parabolic and Vee-Reg are also available. Globe Valves are also metal seated as standard with acceptable leakage rates per API 598.

Check Valves

Check valves, or Non-Return Valves, are also Uni-Directional and designed to stop backflow in the system. Check Valves operate automatically by reaction to the fluid. There are various types of Check Valves in our ANSI range.
Piston or Ball Check Valves are normally spring assisted to force the Piston/Ball onto the seat for a better seal. A low maintenance option with metal seats to limit the amount of wear.
Swing Checks become more standard for sizes 2” and upwards where the valve bore is full and a Piston or Ball would become to heavy for the fluid to lift.
Due to the disc’s resistance against flow, there is a relatively large pressure drop.
Wafer Check Valves are also available, per API 594 design, to fit between flanges. Smaller in design and therefore cost effective the Wafer Check is available with Metal or Soft Seats.

Available in sizes ½” to 2” in ANSI Classes 150LB to 4500LB
Designed per EN ISO 15761, BS5352, API 602 and ASME B16.34

Modifications include Actuation, Stem / Cryogenic Extensions, Pipe Pups & Soft Inserts

Ball Valves

Ball Valves Bi-Directional and used for On/Off Operation, without pressure drop, where zero leakage is a must. Lever Operators will show the position of the Ball and these Valves are available in Full Bore or Reduced Bore across all sizes from ½”. Ball Valves are generally firesafe to avoid damage to soft seats and for safe use on gas applications.
Ball Valves come in Floating Ball or Trunnion Mounted design

The soft seats hold the Ball in place and when closed the flow will press the Ball into the soft seats for a zero leakage seal.
Available in sizes ½” to 12” in ANSI Class 150LB to 1500LB
Designed per BS5351 and firesafe to API 607, API 6FA or BS6755 Pt2
Ends Connections NPTF, SW, BW, RF or RTJ
Materials WCB, LCC, CF3(M), CF8(M), CF8C, CN7M.
Trims in Stainless Steel, ENP, 17.4PH with Seats PTFE, RPTFE, Nylon, Viton or PEEK
Special materials also available : Duplex, Super Duplex, Monel, Hastelloy, Titanium, Inconel, Incoloy, 6MO
Modifications include Gearboxes, Actuation, Stem / Cryogenic Extensions & Pipe Pups

For larger sizes / higher pressure applications a Trunnion Mounted design is standard. The seats are spring energized for double block & bleed design. By supporting the Ball on a Trunnion, the operating torque can be reduced to approximately two-thirds of a floating Ball.
Available in sizes 2” to 36” in ANSI Classes 150LB to 4500LB
Designed per API 6D and firesafe to API 607, API 6FA and BS6755 Pt2

Butterfly Valves

Butterfly Valves are quarter-turn valves and can be used where space is limited. Wafer Pattern are designed to fit between flanges. Operation by lever can show the disc position, which when fully open offers limited resistance to the flow. Gear Operators are used for larger sizes.
Resilient type will have soft seats, high performance is usually double eccentric and tricentric are usually with metal seats.
The varying designs allow for tight shut-off or throttling service.
Available in sizes 2” to 36” in ANSI Class 150LB to 2500LB
Designed to API 609, BS 5155, MSS-SP-67 and firesafe to API 607 where applicable
