1/2" 1 inch DN20 DN25 1.0MPa Back Pressure Valve Features

• Made from durable ABS plastic,High quality Nitril-Bruna N seal,Universal design works with multiple applications

• Check valve is used in fluid system to prevent reverse flow fluid, or used in pneumatic system to prevent reverse flow of compressed air

• This check valve keeps the water from flowing back to the pump and prevents the pump from rapid cycling, extending the life of the pump
