Applications
HY2 sanitary constant pressure valve is used in stainless steel pipe systems.
HY2-1 sanitary constant pressure valve maintains a constant pressure at the inlet port of the valve in the process pipe. It is used at the rear of separators, heat exchangers, and used as an overflow valve.
HY2-2 sanitary constant pressure valve maintains a constant pressure at the outlet port of the valve in the process pipe. It is used at the front of filling or bottling machines.
Operating Principle
HY2 sanitary constant pressure valve is remotely controlled by means of compressed air. The valve can be operated without a transmitter and requires only a pressure regulating valve for the compressed air and a pressure gauge in the product line. A diaphragm/valve stem system can quickly response to any pressure changes of the delivery products, and change the valve stem position accordingly in order to maintain the default pressure value.
HY2-1 sanitary constant pressure valve is open when the product pressure increases and vice versa. HY2-2 sanitary constant pressure valve is closed when the product pressure increases and vice versa. (The operating principle is shown as follows.)
