CSA XLC 321 421 surge anticipating/pressure relief valve

The CSA Model XLC 321/421, installed in derivation from the main line, will act as a protection of the system against the devastating effects of water hammer caused by pump failure. Thanks to a circuit composed of two pilots, hydraulic accelerators and CSA exclusive flow control stabilizer, the valve will serve both as a pressure relief, in case of rise of pressure, and as an anticipator of water hammer in case of pump failure providing the valve with a response time almost instantaneous.
