Features & Advantages:
With the new Model J-B low pressure ESV, activation to raise the piston and drop the clapper occurs when the pressure acting on the piston drops to the low set point. The spring force overcomes the piston force and buckles the pin – moving the piston up to release and close the valve clapper. Set pressure as required. Rody rating to be determined by the maximum pressure possible after the valve closes.
