Our Product Range

Twin Plate Sprung Disc

Nozzle Check Swing Type

• Available in a wide range of materials• Standard, High Performance, Lined and Plastic


Twin PlateTwin Plate design is based upon two spring loaded plates anchored on a centrally positioned hinge pin. These components are housed within the valve body.

Note :

Examples of common options:• Seating can be soft (for zero leakage) or metal-metal• Lugged version• Retainerless or retaining plug design• Can be installed in any orientation


Sprung DiscSprung Disc valves, typically, have four main components: body, disc, spring and spring retainer.

Examples of common options:• Cracking pressure can be tailored to suit customer requirements by

sizing a spring to suit.• Seating can be soft (for zero leakage) or metal-metal• Valve can be installed in any position (Orientations other than

horizontal require engineering input to compensate for disc weight and flow direction).


Swing Type

Swing type check valves can contain as little as two main components but generally consist of a body, a seat and a disc.

Swing type wafer check valves have the advantage that they are of a compact design and low cost in comparison to their full bodied variants.Examples of common options -:

• Seating can be soft (for zero leakage) or metal-metal• Disc’s can be spring loaded • External lever and weight • Lugged version• Full bore version


Nozzle CheckThe Abacus Nozzle Check Valve provides an energy efficient solution to backflow problems in piping systems.

• Sizes from 2” to 60” diameter• Pressure ratings from ASME Class 150 through to 4,500 and up to API

10,000 • End connections: RF, RTJ, BW, compact flanges and clamp connectors• Wide variety of body and trim materials • Design standards: ASME B16.34, API 6D• Face to face : API 6D, API 594, Manufacturers Standard
