8. final seal is made when the 120 deg poppet taper contacts the seat in the valve body Relationship of Product Pressure to Control Air pressure There is a pressure balance between the Product Pressure and the Control Air Pressure This balance is determined by the ratio of the projected poppet area to the air cylinder area The ratio is 1 psig of control air pressure to balance 13 psig of product pressure For the valve to operate reliably the force available from the air cylinder must be greater than the force available from the product pressure Loctite recommends that the product pressure be less than 10 times the control air pressure 3 Instructions J Safety Precautions Read and observe before working on valve Wear protective gear safety glasses gloves aprons etc as required Make sure that the control air pressure is zero and that air is off and no compressed air is trapped in the air lines Make sure that the product pressure is zero and that product is off and that no product under pressure is trapped in the product supply lines Product under high pressure can penetrate skin and other organs Always position the dispense nozzle so that it will not discharge in a dangerous manner Likewise position any disconnected hoses so that they will not discharge in a dangerous manner Installation This valve requires a source of pressurized product and a 4 way pneumatic valve to operate 1 Turn all utilities
