Blow-down Valve

Bottom Blow-down Valves

The valve is usually installed directly at the bottom of the boiler. It mainly uses the pressure of the boiler itself to regularly discharge particles, dirt and other deposits at the bottom of the boiler to prevent the blockage of pipelines.

Continuous Blow-down valves

The valve is mainly used in boiler water continuous discharge, the purpose is to control the content of high pressure boiler water dissolved chemicals, prevent boiler water saturation after dissolved salts, in order to recycling, high pressure boiler water discharge often discharge into the flash tank storage for other low voltage application, continuous discharge of boiler water can be directly applied to detect the contents of the chemical constituents in the water.

Blow-off valves

The valve is mainly used for quick purge and discharge of solid particles in boiler lines and discharge of boiler condensate, etc. Y - shaped structure is usually used, good flow performance, not easy to accumulate solid particles.

Angular body structure, venturi structure are adopted for the valve seat to increase the flow cross section area at the outlet of the valve, reduce the flow rate, increase energy loss, seat surface hardening treatment, and extend the service life

Stem & spool adopt integral design (high energy conversion), spool guide change to sleeve guide, can withstand higher pressure difference

The valve core adopts CASCADE multi-stage step-down structure to effectively avoid cavitation erosion.
