Castle Dual Plate Check Valves are light and compact wafer type check valves that are designed for HVAC and general service applications. Dual plate check valves consist of two spring-loaded plates close when the flow decreases, without the necessity of reverse flow.

• Castle Dual Plate Check Valve minimizes the cracking in the valve and reduces pressure drop in the valve.
• Spring loading on the plates assists in the closing of the valve which ensures tight sealing and it minimizes slamming.
• If a Check Valve closes without any reverse flow then water hammer can be eliminated. Since, the Castle Dual Plate Check Valve closes when the velocity of flow is reduced to zero, before the flow gets reversed. Hence, water hammer is eliminated.
• Castle Dual Plate Check Valves are very flexible in installation. Due to the Spring Action, the valve can be installed both horizontally and vertically.
• The raised profile of the soft seat enhances the sealing

Castle Wafer Type Check Valves are used in pipelines to prevent backflow of the fluid. These valves are fast acting in closing, thereby maximizing protection to prevent the adverse effect of the back-flow. Opening and closing of the valve takes place at an extremely low-pressure difference over the valve disc. The connection of the eccentric disc shaft with the soft seat embedded in the body ensures a positive shut off of the returning medium.

• Wafer Type Check valve weighs much less as compared to the conventional flanged end Swing Check valves.
• Due to short overall length it can be easily installed in horizontal or in vertical pipeline without any special pipe support.
• The seat is fitted in the body in order to prevent contact with the flow, which results in longer life of the seat.
• Our Wafer Type Check Valve has minimum head loss due to large size of the orifice. The Large orifice reduces head loose of the pump and thus saves energy.
• Short face-to-face dimension of the valve makes it easy to install between standard gaskets and line flanges. Low Pressure drop

• SS body and SS flap: DN40 to DN600
• CI body and SS flap: DN40 to DN600
• CI body and MS/EN3 flap: DN250 to DN600

Castle Motorized Butterfly Valve comprise of a butterfly valve that is mounted by an electrical quarter turn actuator with manual override. Adhering to the function of a Hand Operated Butterfly valve, these are ON/ OFF type valves. Castle Motorized Butterfly Valves are BMS compatible.

The major reason for the success of Castle Motorized Butterfly Valves is that the Butterfly Valves chosen to mount the actuator are specially designed low torque Butterfly Valves. This enables long life of the actuator as the load on the electric motor is resisted by the easy opening and closing of the disc of the Castle Butterfly Valve.

Dynamic Pressure Independent Valve acts as a replacement to three different valves that is a two-way valve, a regulating valve and a valve to control differential pressure.

For a manual-balancing valve, it requires to be balanced and for that it requires to manually balance each valve and thus is a time-consuming job. On the other hand, the DBIPV responds to the changes in pressure that results in maintaining the desired flow. Being a multifunctional valve, it reduces the number of valves purchased by the consumer, as it is a combination of three valves. The overall cost of the system is reduced as the piping size required is smaller and they eliminate the requirement of the complexed return piping.
