Piston Valve
Piston valve was Innovated by replacing the disk and seat of a conventional globe valve with a cylindrical piston and two resilient, replaceable sealing rings. Constant research and development have resulted in sealing rings that provide the piston valve with an extraordinary ability to seal line pressure and prevent leakage to the atmosphere. Independent testing laboratories have subjected piston valves to API fire tests and Helium leak tests. The piston valve has out-performed other generic valve types in these tests; and these results have been consistently confirmed by extraordinary performance in customer installations.:
- Larger effective sealing area
- Leak proof isolation - Class 6 shut off achieved.
- Durability - Piston unexposed to media
- Absence of Gland & Seat
- Maintenance friendly - Uniform sealing rings on both the sides & maintenance can be done without removing the valve from the pipe line. (On-line Maintenance)
- User Friendly - It does not need Valve Key
- The Only Scrap Free Valve
- Self Lubricating
- Self Cleaning
