Pentair launches new POPRV

Published by
LNG Industry,


Pentair Valves & Controls has announced the launch of an improved design of its pilot-operated pressure relief valve (POPRV) model for LNG storage in on- and offshore applications.

The Anderson Greenwood 9300H offers increases flow capacity by 30%, enabling the design and construction of larger storage tanks, without the need to increase valve sizes. The compact new model also minimises equipment footprint, which is especially critical for LNG vessels where space is limited. The valve’s increased robustness and durability also provide significant savings on overall maintenance costs, as it requires less frequent and easier repair services.

The valve can efficiently and quickly relieve pressure without the need to increase its size, offering LNG carrier owners and plant operators design flexibility.

The 9300H model comes in sizes from 2 x 3 in. to 12 x 16 in., with sturdy body casting and simplified trim design for easier maintenance. Its pilot, mounted directly on the valve cap, provides a lower and more compact valve profile and increases its sturdiness for more stable flows. This shorter body design is versatile and can accommodate both on- and offshore storage requirements. In addition to its increased flow capability, the new valve handles a large temperature range and features a self-draining body and low sensitivity to back pressure within the exhaust piping. The valve also reduces the possibility of leakage by enhanced seating forces and improved seat design.

Jean-Paul Boyer, Senior Regional Product Manager EMEA, Pressure Management Group at Pentair Valves & Controls, said: “The changes in the LNG market have led ship and plant managers and their suppliers to increase tank sizes for bigger flow capacity and performance. However, the need for small and reliable equipment still remains the same. Pentair’s valve expertise addresses the industry requirements of operators and end users with the Anderson Greenwood 9300H POPRV. We have carried out extensive testing to develop a valve design that evenly distributes more flow and contains pressure under varying conditions, without increasing its size. We bring extensive application experience in the LNG sector, which enables us to improve and optimise critical valve technology. Working closely with our customers, we continue to support future developments in LNG and put the needs of LNG vessel designers, builders and operators at the forefront of what we do.”
