Hard seal : -15°C - +250°C

Applications
For industrial water, water treatment, water supply, pumping station and other fields.
If you have special technical needs, please consult the company.

Product features
  • The valve is larger than the nominal pipe diameter of the full flow path, allowing excellent flow capacity, valve pressure loss is low.
  • When the valve plate is near to close, the flow passage Narrows, so that the flow rate in the pipeline rises, and the fluid washes the valve plate and other sealed positions, effectively increasing the valve life and ensuring long-term zero leakage.
  • Through the action of gravity on the valve plate, reduce the velocity of medium surge, press the valve plate to the closed position, timely closing the valve can reduce the water hammer.
  • Hydraulic or automatic control system can be installed on the side of the valve body to better prevent countercurrent, reduce water hammer influence and protect the pipeline.

Applications
Body plate materials available: cast iron, ductile iron, carbon steel, stainless steel, copper and special alloy (cast iron, ductile iron, carbon steel surface resin coating)
The product is suitable for water supply, drainage, hvAC system, can be installed in the pump outlet. Can be used for horizontal or vertical installation.
If you have special technical needs, please consult the company.

Product features
  • Completely sealed; Reliable performance; Convenient installation; Good diversion effect; Prevent the damage of medium backflow and water hammer effect.
  • Full flow path with valve larger than nominal pipe diameter, providing superior flow capacity and effectively reducing water hammer effect.
  • The use of the valve spring can achieve a quick close, with a very reliable reverse function.
  • The stem of the disc fully guides the precision machined disc to seat to ensure that the disc is properly aligned and closed to the seat.
  • Optional soft seal elastic base ensures zero leakage of seal.


CV53 Nozzle Check Valve
Design standards :
 EN12334
Connection  standards :
 EN1092, ISO 7005, ASME B16.1
Face to face :
 EN558 (48 serial , 16 serial )
Testing standard : 
 EN 12266-1
Working pressure : PN10/16/25 : DN50-DN300
Working Temperatura :
 Soft seal : -15°C - +130°C
Hard seal : -15°C - +250°C

Applications
The material of valve body and spool available : cast iron, ductile iron, carbon steel, stainless steel, copper and special alloy (cast iron, ductile iron, carbon steel surface resin coating)
The product is suitable for water supply, drainage, hvAC system, can be installed in the pump outlet and other low water hammer or low noise requirements of the occasion.
Can be used for horizontal or vertical installation.
If you have special technical needs, please consult the company.

Product features
  • Completely sealed; Reliable performance; Convenient installation; Good diversion effect; Prevent the damage of medium backflow and water hammer effect.
  • Full flow path with valve larger than nominal pipe diameter, providing superior flow capacity and effectively reducing water hammer effect.
  • The use of the valve spring can achieve a quick close, with a very reliable reverse function.Suitable spool and seat fit shape can effectively reduce noise. When the pump stops, the spring can cause the spool to move slowly towards the end of the pump closure, so as to achieve silent closure.



CV6 Ball Check Valve
Design standards :
 EN12334
Connection  standards :
 EN1092, ISO 7005, ASME B16.1
Face to face :
 EN558 (48 serial)
Testing standard : 
 EN 12266-1
Working pressure : PN10/16 : DN50-DN300
Working Temperatura :
  -15°C - +130°C

Applications
Valve body materials: cast iron, ductile iron, carbon steel, stainless steel, copper and special alloy (cast iron, ductile iron, carbon steel surface resin spraying)
The products are suitable for water supply, drainage, wastewater treatment and other working conditions
Can be used for horizontal or vertical pipe installation.
If you have special technical needs, please consult the company.

Product features
  • The valve body is a full flow path; The sphere moves in a smooth orbit.
  • Valves have small pressure losses; The floating sphere can be cleaned automatically.
  • All metal valve balls are covered with all rubber.
  • The valve passes through its valve ball to prevent piping from going backwards. As the fluid passes, the fluid pushes the valve ball from the inlet into the channel to allow the fluid to pass. If there is no positive flow, the ball will fall due to gravity, so that the valve inlet medium flow is blocked by the valve bal
  • Resin spray treatment inside and outside valve.
