Product Description
What is a China Double Flange Check Valve?
A China Double Flange Check Valve is a type of sliding gate valve used to control the flow of fluids like water, steam, gas and chemical slurries through pipes. It consists of a wedge-shaped gate or disc that slides vertically in a ground seal design to open or close the passageway.
Features of China Double Flange Check Valve
- Body: The main China Double Flange Check Valve body is made from ductile iron which is strong yet can withstand impact without fracturing.
- Gate: The gate, which is the moving part that slides to control flow, is also made of ductile iron for its strength and long duty life.
- Seat: An elastomeric sealing surface ensures a drip-tight shut-off when the gate is closed against it with static or dynamic pressures.
- Bonnet: An enclosure bolted to the top of the valve houses the operating stem components to protect them from the process fluid.
- Stem: The stem transmits manual or actuator forces to raise/lower the gate. It threads into a nuts which rotates to open/close the gate.
- Flanges: ANSI/ASME standard flanges on either end allow for easy bolted installation between pipe flanges.
- Coatings: Ductile iron valves from Wholesale China Double Flange Check Valve Manufacturer often receive external and internal protective coatings to defend against corrosion.
Utilizations of China Double Flange Check Valve
- Municipal Water Systems: Often utilized to regulate flow and isolate sections for maintenance within drinking water distribution networks.
- Wastewater Collection: Vital for managing flow in sewers, pumping stations, and treatment plants.
- Power Plants: Critical for controlling steam flow between boiler, turbine, and flash tank vessels.
- Pulp & Paper Mills: Essential for managing process fluids like brown stock, white water, and bleaching chemicals.
- Mining Operations: Reliable for underground slurry and water pipelines facing abrasive loads.
- Manufacturing Facilities: With sturdy ductile iron construction, China Double Flange Check Valve proves ideal for flow regulation in industrial environments such as chemical, food and beverage, and refineries.
