Single Plate Check Valve Manufacturer in India
A single plate check valve uses one hinged closure plate supported within the valve body to allow forward flow and restrict reverse flow. Its compact construction provides a practical non-return arrangement for piping where a single-disc closure mechanism is suitable. Speciality Valve manufactures single plate check valve configurations in wafer, lug and flanged arrangements, with spring assistance, seat construction, body material and closure characteristics selected according to pressure, temperature, fluid and installation requirements.
Single Plate Check Valve Technical Specifications:
Disc, Hinge and Seat Construction:
Single disc: Provides one primary moving closure element.
Hinge pin: Controls disc rotation and transfers dynamic loading into the body.
Spring assistance: Can accelerate closure as forward flow decreases.
Seat ring: Provides the sealing interface between disc and body.
Metal seating: Suitable for selected higher-temperature or demanding services.
Resilient seating: Can provide tighter closure where elastomer compatibility is established.
Disc travel: Depends on body geometry, hinge arrangement and differential pressure.
Body Material Options:
Material Grades:
Installation and Connection Arrangement:
Single Plate Check Valve Service Applications:
Pump Discharge Lines: Prevents reverse flow toward the pump when flow stops.
Vertical Piping: Suitable for installations where the valve design and flow direction support reliable plate closure.
Water Distribution Lines: Provides automatic non-return protection in pumping and transmission systems.
Process Fluid Lines: Used for compatible liquids and gases where simple automatic backflow prevention is required.
Compressor Discharge Piping: Helps prevent reverse flow into connected compression equipment.
Inspection and Testing:
API 598: Pressure testing and inspection requirements for check valves.
ASME B16.34: Pressure-temperature, material, testing and marking requirements where applicable.
ASME B16.10: Face-to-face dimensions where covered by the selected construction.
ISO 5208: Leakage testing where specified by the project.
Inspection: May include material verification, dimensional inspection, shell testing and closure testing.
If the line has limited installation space, share the required size, flange arrangement, pressure class, operating medium, temperature and closure requirements with Speciality Valve to discuss the appropriate plate, seat and body construction and obtain a quotation.
