Retainerless design

Our single plate check valves are offered as retainerless in wafer, lug, flanged, hub end, butt-weld end and thread end body style.

Certificate

All products registered by LR's in accordance with CE/PED.
API 594 and API 6D certificates issued by the American Petroleum Institute.

Inherently fire-safe design

All our check valves are inherently fire-safe due to the valve design, material and construction. In case of fire, both resilient seats and metal seat valves provide metal-to-metal sealing performance.

Lightweight and reduced size

Installation costs are greatly reduced by our lightweight and minimal space requirements. The compact design minimizes the distance between flanges and is easily installed between all flanges.

Horizontal/Vertical installation

Unlike most traditional swing check valves, our check valves are ideal for both horizontal and vertical pipeline installation.
