Special Features :

• The piston always held by value ring in either open or closed position resulting in no vibration.
• It can be used as bi-directional valve.
• However it is preferred to install the valve such that pressure acts below the piston.
• Value ring used for sealing is made up of packing, hence the piston valve acts as a soft seated valve.
• The piston valves used in many brass instruments
• Also used in many stationary steam engines and steam locomotives

Shutoff Rating :

Zero Leakage for Soft Seated & Metal Seated as per API 598 or relevant STD.

Special Features :

• Low pressure drop increases energy savings.
• Lower maintenance costs; fewer moving parts.
• Flexibility to cope with variable flow conditions.
• Smaller footprint than conventional check valves.
• Allow easy field retrofitting of various product lines.
• Reduce down time and loss of production due to failure.
• Protect pumps and compressor equipment from damage.
• Eliminate chatter and reduce the possibility of sudden valve failure
• Shutoff Rating
• Zero Leakage for Soft Seated & Metal Seated as per API 598 or relevant STD.
• Wafer Type, Flangeless, Sandwich Pattern.
• Suitable to mount between two flanges
