Price of suction check valve

Exhaust check valve is a type of valve used to prevent the backflow of medium in pipelines, mainly used in systems that require exhaust (or vacuum) environment (such as turbine exhaust systems, vacuum pipelines, condensate systems, etc.).

Its core functions are:

Unidirectional flow: allows the medium (gas, vapor, or liquid) to flow in a single direction, preventing reverse reflux.

Vacuum protection: Maintain stable system pressure under pumping or vacuum conditions, prevent external air or medium from flowing back into the equipment, and avoid damage to the unit (such as the steam turbine) or affecting system efficiency.

Application scenarios of suction Check valve

Water supply and drainage engineering

Urban water supply system: Soft sealed Gate valves or butterfly valves are used for cutting off and regulating water plants and pipelines to prevent water leakage.

Wastewater treatment: Rubber lined Ball valves or corrosion-resistant butterfly valves are suitable for impurities and corrosive media in wastewater.

HVAC system

Heating pipeline network: Cast steel soft seal gate valve controls hot water circulation, and soft seal reduces leakage caused by thermal expansion and contraction;

Air conditioning water system: Butterfly valves or ball valves regulate the flow of chilled water, ensuring reliable sealing and minimal space occupation.

Chemical and Food Industry

Chemical pipeline: PTFE lined soft sealed ball valve for transporting acidic and alkaline solutions, corrosion-resistant and zero leakage;

Food and medicine: Sanitary grade cast steel butterfly valves meet sterile requirements and are used for material transportation.

Energy and Light Industry

Compressed air system: Soft sealed ball valve for quick opening and closing, controlling the on/off of gas source, rubber seal to prevent gas leakage;

Paper industry: Soft sealed knife gate valve resistant to fiber winding, used for cleaning and cutting pulp pipelines.
