Check Valves Engineering Guide

Check Valves

Check Valves are selected for backflow prevention on pump discharge, compressor systems, pipelines, water systems and process equipment. The correct configuration depends on pressure class, temperature, media, materials, end connection and inspection requirements. Choose swing, dual-plate, axial-flow, piston or non-slam designs by flow direction, closing speed, surge risk, pressure class and installation orientation.

Typical service
Backflow prevention on pump discharge, compressor systems, pipelines, water systems and process equipment.
Selection points
Choose swing, dual-plate, axial-flow, piston or non-slam designs by flow direction, closing speed, surge risk, pressure class and installation orientation.
Applicable standards
API 594, API 6D, BS 1868, ASME B16.34 and API 598.

Plant application

Pump-discharge backflow prevention

Function
Stops reverse flow on pump discharge. Closing characteristic must match the pump and system inertia.
Medium family
Water, hydrocarbons or process fluids on the datasheet.
Pressure & temperature
Family listing range is DN15–DN600. Do not treat DN1200 / 56 in as a check-valve default.
Applicable standards
API 594, BS 1868, ASME B16.34 and API 598 as applicable.
Send with RFQ
Size, class, swing/dual-plate/lift, installation orientation, flow and closing-speed concern.
Related application

Pipeline / compressor non-slam duty

Function
Non-slam or axial-flow designs where surge or slamming is a project concern.
Medium family
Gas or liquid pipelines listed on the datasheet.
Pressure & temperature
Closing speed, cracking pressure and orientation confirmed against the project, not a catalogue claim.
Applicable standards
API 6D / API 594 / ASME B16.34 when the selected design is specified to those standards.
Send with RFQ
Flow, density, reverse-flow risk, preferred non-slam type, class, ends and test scope.
Related application

Cooling-water and utility check

Function
Simple backflow prevention on plant utilities.
Medium family
Cooling water, firewater or utilities — coating/lining only when specified.
Pressure & temperature
Pressure class typically 150–600 on listed check SKUs; confirm the selected model.
Applicable standards
API 594 / BS 1868 / API 598 as applicable to the SKU.
Send with RFQ
DN, class, type, ends, orientation and hydrostatic test requirement.
