Self-actuated differential pressure control valve:
Differential pressure control valve for the double-flap structure, stem unbalanced force is small, compact structure, for heating (air conditioning) water system, was charged with a constant pressure system, and has the following characteristics:
1, constant pressure control system has been;
2, support was charged with self-regulation within the system;
3, absorbing external network pressure fluctuations;
4, the use of advanced non-level voltage structure, control over adjustable pressure of up to 25: 1;
5, with automatic elimination of blocking function;
6, flange dimensions conform to GB4216.2 in gray cast iron flange dimensions.
