Dual Plate Wafer Check Valve , Flangeless API594 Standard Wafer Type Check Valve

Double Plate Flangeless API594 Standard Wafer Check Valve For Horizontal Vertical Install

Dual Plate Check Valve VS Full bodied Swing Check Valve

1. COST SAVING DESIGN

The dual plate check valves can be as little as one fifth the weight of the equivalent full-bodied swing check valve. This results in savings in initial cost, space and pipe support element installation.

2. REDUCED LINE SHOCK

To eliminate line shock, check valves must close as quickly as possible prior to the flow having an opportunity to reverse. As each of the discs in dual plate check valves are only half the size of that of a full bodied check, they experience reduced fluid drag and can move more quickly to the closed position. Their swing radius is one half that of the conventional check valves. The leading edge distance from open to closed position is halved, in turn reducing the travel time by 50%.

3. LOWER PRESSURE DROP AND INCREASED Cv FOR VALVES 24” AND LARGER

Dual plate check valves are designed such that the discs are hinged at their sides like a door, eliminating the effect of gravity. Consequently, very little energy is needed to open the valve and maintain this position, resulting in lower energy costs.

Design Features:

• Body surface with uninterrupted gasket surface
• Retainerless Body Design
  With no drilling through the body wall, the TEKO dual plate check valve is inherently fire safe
• Short In design and only one fifth of the conventional swing check valve, saving the cost.
• Quick closing for no-slam operation.
• Heavy duty shock bumpers on the back of disc prevent the discs form striking the stop pin, ensuring internal components have an extended cycle life with minimal wear under most severe services.
• A high torsion spring ensures the valve closes as quickly as possible.
