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. Forged SteelAvailable in sizes ¼” to 2” in ANSI Classes 150LB to 4500LB. Cast SteelAvailable in sizes 2” to 72” in ANSI Classes 150LB to 2500LB Special materials also available : Duplex, Super Duplex, Monel, Hastelloy, Titanium, Inconel, Incoloy, 6MO Modifications include Actuation, Stem / Cryogenic Extensions, Pipe Pups & Soft Inserts |

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. Forged SteelAvailable in sizes ¼” to 2” in ANSI Classes 150LB to 4500LB. Cast SteelAvailable in sizes 2” to 24” in ANSI Classes 150LB to 2500LB Special materials also available : Duplex, Super Duplex, Monel, Hastelloy, Titanium, Inconel, Incoloy, 6MO Modifications include Actuation, Stem / Cryogenic Extensions, Pipe Pups & Soft Inserts |

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. Forged SteelAvailable in sizes ½” to 2” in ANSI Classes 150LB to 4500LB Cast SteelAvailable in sizes 2” to 36” in ANSI Classes 150LB to 2500LB Special materials also available : Duplex, Super Duplex, Monel, Hastelloy, Titanium, Inconel, Incoloy, 6MO Modifications include Actuation, Stem / Cryogenic Extensions, Pipe Pups & Soft Inserts |

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 Floating Ball DesignThe 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. Special materials also available : Duplex, Super Duplex, Monel, Hastelloy, Titanium, Inconel, Incoloy, 6MO Modifications include Gearboxes, Actuation, Stem / Cryogenic Extensions & Pipe Pups Trunnion Mounted DesignFor 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 Special materials also available : Duplex, Super Duplex, Monel, Hastelloy, Titanium, Inconel, Incoloy, 6MO Modifications include Actuation, Stem / Cryogenic Extensions & Pipe Pups |

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. Special materials also available : Duplex, Super Duplex, Monel, Hastelloy, Titanium, Inconel, Incoloy, 6MO Modifications include Actuation and Stem Extensions. |
