Applications 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.)
