The Circle Seal Controls model 2262T1-8MM Check Valve is a reliable design that combines the functional advantages and operating economies of perfect sealing with small package size for low pressure systems where flow rates are small.

How it Works

Features & Benefits:

  • Quick opening / positive closing: opening pressures as low as 0.1 PSIG
