Dual plate check valve

The dual Plate Check Valve is an all purpose non return valve that is much stronger, lighter in weight and smaller in size compared to a conventional swing check valve or life check valve. Aquaseal Chek Valve is a soft-seated dual-plate check valve that conforms to API 594. The valve with cast iron body is available in sizes 2” (mm) to 12” (3mm), in PN 1 PN and ASME Class 1pressure ratings. Zhejiang Naibang Valve CO. Dual Plate Check Valve.

About Us Honor Workshop.

Additionally, the total cost of a dual plate check. Wafer, Flange Solid Lug, Buttweld en Hub en and in an extensive range of sizes, pressure classes and materials. Spring loaded plates assist valve closing to ensure tight seal and minimize slamming.

Buy Top Products On eBay. Our dual plate check design weighs a fraction of the full-bodied Swing or Piston Check valves. The SCV designs offers many features and options beneficial for oil, liquid gas, and liquid applications. DUAL PLATE WAFER CHECK VALVE (IRON AND CAST STEEL) Advantages of Design The main purpose of the DUAL PLATE WAFER CHECK valve is to perform the work of almost any conventional valve.

However, being smaller makes it lighter an therefore, is more cost efficient to purchase, install and maintain.

Recommended frequency of use is at least once a week. BB dual - plate check valves are wafer-type valves with a short overall length. Their excellent hydrodynamic properties result in very low pressure losses. Their lower weight brings advantages during installation, transport and storage.

Leak-free, tight sealing, protection against reverse flow and minimal flow direction changes are at the core of Flowserve check valve designs. The valve is available in the sizes, pressure classes and configurations required to meet the most demanding of applications. Our product range includes, but is not limited to: Sizes: 2. That means flow is often restricted with a wafer check valve.

Swing check valves on the other han have a molded body that creates room for the disc to swing open fully, thus allowing full flow. End connection of this valve is mainly Wafer En Wafer Lug End and Flanged End. The compact design features non-slam spring-assisted closing.

The dual-plate check valve opening and closing member is opened or closed by the medium flow and the force to prevent the back flow of the valve from being called a check valve. Check valves are automatic valves , mainly used on pipes with one-way flow of media, allowing only. All US Valve check valves are tested to API 5and must meet or exceed all applicable API, ANSI and ASTM Standards. This type of check valve is simple assembly of 1) dual - double flap or can say door, 2) single piece casted heavy duty body, 3) spring and 4) stem. In such instances, this will be clearly indicated in the quotation.

DUAL PLATE CHECK VALVE TYPES †On occasions, for technical or delivery reasons, Goodwin may offer valves with retainers.

MSS-SPnow superseded by ANSI B16. Series B ∆Outside profile of bodies may differ from those shown. The RITAG Type ZRD dual plate check valve is the most universal check valve among the nonreturn valves. It is available in a broad spectrum of nominal diameters and nominal pressures.

An important feature of the DUO CHECK valve is that it does not depend on the pressure or flow to center the plates in relation to the sealing surface in order to make the seal. If neede the Style LP can be machined to meet a specific face-to-face requirement.
