he SPFï¼?SPï¼?type digital lock balance-valve is used for balancing the hydraulic regime of the liquid circulation network. It possesses the excellent characters about the control, the blockage, the opening rate display and the opening rate lock. It can save energy and electricity when it is used in the heat-supply system or the air-conditioning system.
he SPF15T-16 style digital lock balance-valve is equipped with inner up-down declining pole, sealed with PTFE. The material of the valve body is forging copper alloy.
There are two mini-pressure measuring valves on the two sides of the valve gate which connect with the intellectual meters with soft pipe, and they can be displayed.
The ZTY 47 (ZY47) type self-operated pressure difference control valve is a kind of valve which can fix the pressure difference automatically and balance the hydraulic regime. It can be used in the centralized heat-supply, centralized air-conditioning and other hydraulic systems.
ZL-4M (ZL47F) series of self-operated flux control valve is a kind of valve that can fix the flux automatically and balance the hydraulic regime. It can be set with different flux according to customers demand and can maintain constant flux by itself. It can be used in some areas that need fixed flux in the water system of centralized heat-supply and centralized air-conditioning to make the whole pipeline regulated at one process and the regulating process simplified into a process of flux distribution. Further it is avoided that the flux re-distribution might need during heat source switching process and thus prevented the hydraulic maladjustment of the pipeline.
