Description
High velocity P/V relief valves for marine cargo tanks. Tank venting and gas freeing solutions for tanker fleet operators.
Did you know
- Tanktech's NEW ISO-HV SERIES of high-velocity P/V valves was introduced around April 2020, building upon earlier ISO-HV models.
- The NEW ISO-HV SERIES represents a high-velocity pressure/vacuum valve within Tanktech's product range, designed for rapid breathing and distinct from rupture pin type valves like the KSRP, which integrates both pressure and vacuum relieving in a single body for easier installation.
- The Tanktech NEW ISO-HV SERIES is chosen for its ability to balance cargo pressure during delivery and temperature changes, prevent seawater ingress into ballast tanks, facilitate air drainage, and provide high-speed pressure drop. It also incorporates fire-blocking mesh to prevent flame passage into cargo tanks, complying with IMO and USCG regulations.
