Check Valves Product List

 

1. TRUE UNION BALL CHECK VALVE(15-50mm)[1/2-2inch]

 

 

• The valve body can be removed from the pipe line by loosening the union nuts at its both ends.

• THE VALVE PARTS CAN BE REMOVED WITHOUT DISCONNECTING THE PIPES, BY
  LOOSENING THE UNIONS ON BOTH SIDES

 

 

 

 

2. SINGLE UNION BALL CHECK VALVE(15-100mm)[1/2-4inch]

 

 
• Backflow Prevention
The valves prevent back fiow in horizontal or vertical lines. They require minimal back pressure to seat completelly.
• Compact and Light
The BALL CHECK and BALL FOOT VALVES are so compact and light that they can be installed in a limited space. They are also easy to maintain,because of minimal internal parts.

• THE VALVE PARTS CAN BE REMOVED WITHOUT DISCONNECTING THE PIPES, BY
  LOOSENING THE UNIONS ON BOTH SIDE.

 

 

 

 

 

 

 

 

3. SWING CHECK VALVE(15-200mm)[1/2-8inch]

 

 

• The SWING CHECK VALVE prevents backflow, thus protecting equipment, such as a pump.

• Being of an swing arm type, the valve gives little resistance to flow.

• The SWING CHECK VALVE is highly resistant to corrosive chemicals, acid and alkaline, because of its
   plastic construction.

• To maintain the SWING CHECK VALVE, only the bonnet lid has to be removed, without taking the body
   out of pipeline.

 

 • PREVENT FLUID BACKFLOW AND PROTECTS PUMP FACILITIES

 • ARM-TYPE CHECK VALVE PREVENTS FLUID RESISTANCE INCREASE.

 • ALL-PLASTIC MATERIAL PROVIDES HIGH RESISTANCE TO CORROSIVE FLUID
   INCLUDING ACID AND ALKALI

 • INTERNAL MAINTENANCE ONLY REQUIRES REMOVAL OF BONNET

 

 

 

 

 

 

4. BALL FOOT VALVE(15-100mm)[1/2-4inch]

 

 
 

• Backflow Prevention

The valves prevent back fiow in horizontal or vertical lines. They require minimal back pressure to seat completelly.

• Compact and Light

The BALL CHECK and BALL FOOT VALVES are so compact and light that they can be installed in a limited space. They are also easy to maintain,because of minimal internal parts.

• INTEGRAL MOLDING WITH SCREEN INCREASES STRENGTH AT CONNECTION AREA.

• FLOW PASSAGE STRUCTURE WITH FLOW FLUID RESISITANCE

• SMALL PARTS QUANTITY AND A SINGLE CONNECTION REDUCE EXTERNAL STRESS
  EFFECTS, ALLOWING HIGH FINISHING ACCURACY

• LIGHTWEIGHT AND SMALL SIZE ALLOW INSTALLATION IN NARROW SPACES AND
  FACILITATE DISSAMBLED CLEANING. 

 

 

 


5. WAFER CHECK VALVE [4-12INCH](80-300MM)

 

• High Strength
Capitalizing on stress analysis, they relieve users of any concern about the strength of resin-made wafer check.

• High Corrosion Resistance
All components contacting fluid are made of resins. In addition, spring are coated.

• Lightweight and compact
Their weight are about one third to one fifth thos of metal valves. With small interfaces, they facilitate piping work.

• Cost reduction
No gaskets are needed when piping. With integrated stoppers, they help reduce cost.
