Single Plate Check Valves (Wafer Type Check Valve)
Design Features
Regent Wafer Type Check Valves has distinct advantages over conventional Swing Check Valves.

• Stronger, Lighter and Smaller size. It weights about 1/8yh weight of conventional valve.
• Structurally Sound
• Hydraulically Engineered.

Flexible Installation
Can be installed in horizontal or in vertical line without any special pipe support. The light weight and short face-to-face dimension of valve makes it easy to install between standard gaskets and line flanges.

Construction
Body and Plates : C.I./C.S./S.S-304, 316/AI. Bronze to ASTM A-126 Gr. B, A-216 GR WCB/CF8M, or any other alloy as per Buyer’s Specifications.

Hing Pin : C.S./S.S. or Buyer’s Specifications.

Seal : Nitrile, Neoprene, EPDM,Viton-A or Metal to Metal.

End Facing : Plain face, Raised Face or Ring Joint Facing

Application : The value is suitable for all types of fluids. Buyers must specify the service condition for selection of suitable material of construction.

Dual Plate Check Valves

• Dual Plate Check Valves are light in weight thus easier handling and self supporting.
• More compact & structurally sound design.
• Can be installed horizontally or vertically.
• Only Check Valve which can be installed for flow upside down due to spring assisted closure.
• Low Pressure Drop and reduced Energy Loss irrespective of Pressure Ratings.
• Streamlined flow way.
• Efficient and Positive sealing under most flow and pressure conditions. Valve closes before flow reversal at zero velocity.
• Inherently Non-Slamming.   No external devices /attachments required.
• Water Hammer almost non-existent.
• Long life and trouble -free operation.

Application
The Dual Plate Check Valves is the most versatile design available in specific materials of construction to suit particular Pressure, Temperature and Fluid Flow Characteristics. Some of the Typical Applications are as follows :

Water
Water Supply Systems, Fire Water Systems, Cooling Water, Chilled /Hot Water Systems, Boiler Feed Water, Sea Water, Potable Water, Raw Water etc.

Hydrocarbons
All applications

Oil & Gas
Onshore/ Offshore, Petroleum, Lubricating oil, Hydraulic oil, Edible Oils, LPG, Sour Gas, Low Temperature Applications etc.

Air & Gases
All Gases like Chlorine, Hydrogen, Nitrogen, Carbon Dioxide (CO2) etc.

Metallurgical & Chemical processes
Sugar, Pharmaceutical, Paper, Cement, Steel, Aluminium, Copper, Zinc, Power and other Industries.
