Dual Plate Check Valves
Product overview
Dual plate check valves are commonly specified as a preferred non-return valve option due to the weight and space saving nature of the design compared to other check valve types. With no leak path to atmosphere, the design also inherently offers a check valve choice with zero fugitive emission potential.
PJ Valves provides a comprehensive range of dual plate check valves that can be engineered to meet even the most stringent leakage rate requirements.

Production range
PJ Valves' dual plate check valves meet API 594, API 6D and API 6A standards dependent on project requirements. All end connection and flange configurations are achievable including solid lugged, double flanged, and hub ends for high pressure applications.
Range
Material scope
PJ Valves believes that every good valve starts with quality raw materials. We are experts in compliance with stringent material specifications including NORSOK, and a wide variety of end user requirements covering both metallic and non-metallic parts.
Increasingly, severe upstream operating conditions mean specifications focus not only on primary valve components, but also elements such as bolting and operator materials. PJ Valves can meet the needs of any project specification through established relationships with our component supply chain.
