Dual Plate Check Valve
- Minimum weight and compact design
- Optional body design (wafer, flanged, welded ends)
- Self retainer hinge
ATV manufactures a full range of wafer dual check for production, processing and transmission applications wherever non-return protection is required.
Dual plate check valve offers the advantage of a more compact design and a lower cost than the other check valves. Dual plate check valves are the preferrable choice in applications that require low pressure drop and rapid response against pressure surge and water hammer.
ATV offers its dual plate valves with flat twin plate design, that allows low pressure drop, fast response time and a superior metal-to-metal sealing capability. Moreover, a self-retained hinge, without external screwed plugs, helps to decrease the leak paths and allows the valve to be fugitive emission free. Different body styles (wafer, flanged, welded ends) are available to meet different pipelines connections.
A large choice of materials is available to meet application requirements: materials are sourced from qualified suppliers on the base of specifications that reflect the industry standards (ASTM, NORSOK, BS, DIN or others), but do also incorporate additional requisitions resulting from long experience.
ATV designs, manufactures and tests its products in accordance with all the relevant Industry standards and codes (API, ANSI, ASME, BS, ISO, NACE, PED and others).
ATV stresses its willingness to produce engineered valves; therefore, it welcomes requests for special size, class and design requirements.
