JRV-SF21 (Pilot Operating Type)
As it is a pilot type, it does not require an auxiliary power source such as compressed air or electricity and has a larger capacity compared to the direct impingement type. There is a wide range of pressure adjustment available. With the built-in "pressure relief valve filter" with a practical design patent No.13137, errors caused by the scale or impurities inside the pipes are prevented. Compatible with disks/ sheets. Leakage: Less than 0.05% of the standard flow
