About This Product

Used as a relief valve for pumps in closed circuits of air conditioning and heating/cooling equipment in high-rise buildings. In the case of an open circuit system, a primary pressure regulating valve is used as the relief valve of the pump, but in the case of a closed circuit system, a differential pressure regulating valve is used because the pump must be operated at a constant flow rate regardless of the load.

■Place of use

・Air conditioning equipment ・Heating and cooling equipment

■Main features

・Used as a pump relief valve in a closed circuit. - An NBR disc is used for the valve body.
