Non Return Valve

Approx. Rs 2,500 / PieceGet Latest Price

Ball Type Check Valves is a non return valve with a very simple and robust design. The heart of the valve is rubber coated ball. The hinge-pin-disc mechanism used in conventional check valves, which is the cause of most operation and maintenance issues such as pressure drop, imperfect sealing, leakage, clogging, etc., is eliminated.

As the pump starts, the ball moves out totally from the flow path, giving a full bore with maximum flow discharge and minimum head losses. As the pump stops, the ball rolls back and seats perfectly on the rounded valves seat ensuring totally leak proof sealing.

Salient Features:

1. Lowest possible pressure drop across all types of check valves.
2. 100% leak proof sealing years over years.
3. Non-clogging and self cleaning as ball rotates during operation.
4. Virtually no wear and tear, no maintenance and longer service life.
5. Higher solid handling capacity due to full bore and straight internal path.
6. Lower head loss-high discharge, reduced pumping time - All leading to Energy Savings.

Clean water, Raw water, Sewage, Slurry, Waste Water, Viscous liquids etc.

Used in industries like:

Fire fighting, Plumbing, Water distribution, Water/Sewage treatment, Irrigation/agriculture, Sewage plants, Steel mills, Power stations, Chemical/process industries, HVAC, Sugar/food industry, Breweries, Mining and many more.

This valve is also available with optional rubber lining.

Dual Plate Check Valve
Dual Plate Check Valves are automatic mechanical valves, which open with a forward flow and shut to a reversal inflow. The key feature of the check valve is to secure the mechanical devices in the pipe system by avoiding the reversing of the fluid. The swing check valve is an economic kind of check valve, but it has a higher slamming effect.
Feature and Benefit of Dual Plate Check Valve.
The Dual-Plate Check Valve is a non-return valve that is comparatively stronger, lighter in weight, and compact in size than the conventional swing control valve or lift control valve.

• Pressure drop in a dual plate check is very low as compared to other check valves.
• Low wear and tear of the seat as it has a design of non-slamming type.
• Water hammers are almost negligible in dual-plate check valves because valve closure does not rely on backpressure and backflow. Each plate, which is half the size of a swing check disc, offers a straight flow path, providing the least resistance. As a result of spring-assisted closing, the valve closure begins as soon as the flow velocity decreases below the intended minimum velocity, and then the closing rate flows into the flow velocity reduction pattern. The valve shuts as the flow rate reaches zero and well before the flow is reversed. This reduces the water hammering.
• Non-Slam Design: The two plates in the Dual Plate Check Valve are mounted vertically in the middle for horizontal installations, completely removing the influence of gravity. Also, the momentum produced as they travel to a closed position is just a fraction of what is developed in a swing check valve. Further due to the spring-assisted closure, the valve shuts as the flow velocity reaches zero and until the flow reversal. When it begins to close, the flow, as such, cushions the plates and the seat, thereby reducing slamming.
• Dual Plate Check Valve Application
• A dual plate check valve is the most suitable type of check valve that can be used for almost any configuration of material and system parameters used in various applications, some of the typical applications are:

• Water systems like boilers, Potable water, Fire safety system, Cooling & Heating water system, etc.
• Petrochemicals: Offshore/Onshore applications, LPG, LNG, Lube oil, Cryogenics, etc.
• Hydrocarbon: In almost all the applications.
• Air & Gas applications like Chlorine, Hydrogen, Nitrogen, Carbon Dioxide, Oxygen, Etc.
• Metallurgical and Chemical Applications: Sugar, Pharmaceuticals, Paper, Cement, Steel, Aluminium, Copper, zinc, etc.
