Product information

The main purpose of a valve is to control media flow through a system. The valve may be used to start, stop, or throttle the flow to ensure safe and efficient operation of the process. Valves are used to optimize the pipeline operating conditions, and can be found in the upstream, midstream and downstream section of the piping.

Gate Valves

Types

  • Bolted Bonnet
  • Welded Bonnet
  • Pipeline Slab
  • Parallel Slide
  • Solid & Flex Wedge
  • Knife Gate

Product information

The function of the gate valve is to start or stop a flow when a straight-line flow of fluid and minimum flow restriction is needed. During use, gate valves are kept either fully open or fully closed. The disc of the gate is completely removed when turned open, allowing contents to pass through. Advantages: a straight through flow of fluid in either direction, low-pressure drop.

Globe Valves

Types

  • Bolted Bonnet
  • Welded Bonnet
  • Pressure Seal - Ball, Plug, Needle, Parabolic, Liner Disc

Product information

Globe valves are linear motion valves that are widely employed to stop, start and throttle flow. Globe valves are designed with a stem that moves up and down to regulate flow inside the valve, a disc (ball, composition, or plug) and seat, which is generally screwed into the valve body. Advantages: good shutoff capability, shorter stroke (compared to a gate valve), can be used as a stop-check valve.

Check Valves

Types

  • Swing Check
  • Ball Check (straight or Y pattern)
  • Piston Check (straight or Y pattern)

Product information

Check valves are also referred to as a non-return valve. Unlike other manually-controlled valves, check valve operates automatically. It prevents back-flow in the piping by constantly keeping fluid flowing in one direction.

Ball Valves

Types

  • Floating
  • Trunnion mounted
  • Double block and bleed

Product information

Ball valves are available in various materials and sizes. They are used for the broadest spectrum of isolation applications and are available in full flow and full through conduits. Advantages: low-pressure drop, quick-acting, straight through flow in either direction, easily actuated, bubble tight shut off & operating torque.

Product information

The butterfly valve is designed for flow isolation and operates at right angles to the flow. Due to the wing-like action of the disk, butterfly valves have slightly reduced flow characteristics and also provide bubble tightness with low operating torque. Advantages: compact and lightweight, very efficient, simple and reliable, good regulating characteristics, low-pressure isolation.
