The core function of the rotary check valves is to prevent dielectric backflow. It is widely used in the following industries:
Oil and gas industry
Application Scenarios: crude oil, refined oil pipelines, natural gas processing unit.
Function: To prevent backflow of media from causing pump reversal or container leakage, avoid equipment damage and safety accidents. For example, in atmospheric pressure and vacuum distillation units at oil refineries, swing check valves can reduce system pressure loss and water hammer.
Chemical industry
Application Scenarios: Pipeline conveying corrosive media such as nitric acid and acetic acid, as well as fertilizer production, chlor-alkali industry, etc..
Function: Valves made of corrosion resistant materials (such as stainless steel, alloy steel) can withstand strong acid and strong oxidizing media, prevent cross contamination and process interruption. In extracorporeal circulation surgery, for example, it can limit blood flow back and ensure safe surgery.
Power industry
Application Scenarios: Feedwater systems and cooling systems for thermal and nuclear power plants.
Function: Keep steam or cooling water flow one way, prevent water hammer and equipment from overheating. For example, multi-disk swing check valves is used in the condensation system of nuclear power plants to disperse the impact of closure and to ensure stability under high frequency start and close conditions.
Metallurgical Industry
Application Scenarios: High-temperature molten metal transport pipeline, metallurgical production processes.
Function: To prevent molten metal backflow, equipment damage and production accidents. For example, in a boiler feedwater systems, it ensures a unidirectional flow of steam or hot water and prevents boiler from being damaged by backflow.
Water Treatment and Water Supply
Application Scenarios: Waterworks, sewage treatment plants, Pump Station, flood control projects.
Function: Prevent sewage backflow, ensure water quality safety and system efficiency. For example, in large reservoir drainage systems, it protects pumps from adverse flows.
Pharmaceutical and biotechnology industries
Application Scenarios: Liquid and gas conveying pipelines, Biological fermentation processes.
Function: Precise control of medium flow direction, prevention of cross-contamination, and stable fermentation environment. For example, in beverage bottling line, it prevents the return of beverages and ensures accuracy and hygiene in filling.
HVAC & Building Industry
Application Scenarios: Chilled water/hot water circulation systems, water supply and drainage systems for high-rise buildings.
Function: Control the direction of water flow, improve the efficiency of the system and ensure the safety of water supply. In HVAC systems, for example, it optimizes cold water circulation and reduces energy loss.
Food & Beverage Industry
Application Scenarios: Material transport pipeline with high hygiene requirements during production.
Function: prevent material from backflow in different stages, avoid cross-contamination and guarantee product quality. In liquefied gas pipelines, for example, it keeps gas flowing in one direction and prevents leakage accidents.
Paper & Mining Industry
Application Scenarios: Slurry transport pipe, slurry processing flow.
Function: Suitable for medium containing solid particles or high viscosity to prevent equipment blockage and process interruption. In mining industry, for example, it can handle complex media such as mud to ensure production continuity.
Municipal and Mechanical Equipment Supporting Industry
Application Scenarios: urban water supply network, mechanical equipment hydraulic system.
Function: To provide reliable unidirectional flow control and prolong the service life of equipment. In the electronics industry, for example, it ensures the stability of hydraulic systems in sophisticated equipment.
