READ MORESince its establishment in 2004, our company has been committed to becoming an outstanding supplier in the field of breathing valves, safety valves and glass sight glasses. With more than 20 years of in-depth understanding and focus on industries such as reducers and air compressors, we have developed into a comprehensive enterprise integrating R&D, production and sales. Our team consists of 5 experienced technicians and nearly 30 skilled operators, who are committed to providing customers with the best products and services.
Our wide range of products, including breathing valves and safety valves, are designed for various industrial applications to ensure that the pressure and gas flow of the equipment during operation are accurately controlled, thereby improving overall safety and efficiency. Glass sight glasses are made of high light transmittance and high pressure resistance materials, providing clear and intuitive visual monitoring effects, so that users can understand the internal status of the equipment at any time.
Aluminum alloy oil gauges, oil mirrors, and oil level mirrors are used to monitor the oil level of the equipment to ensure that the equipment is in the best lubrication state and extend its service life. The vent cap and exhaust cap effectively remove the gas accumulated inside the equipment, keeping the equipment running smoothly and efficiently.
The air filter filters impurities in the air, provides a clean air environment for the equipment, and improves the overall operating performance. Pump accessories such as pressure vent caps, oil cups, positioning oil cups, L-type oil cups, etc. provide comprehensive accessory support for various pump equipment to ensure the continuity and stability of equipment operation. Hydraulic oil tank accessories such as reducer accessories and air compressor accessories provide customized accessory solutions for the characteristics of reducers, air compressors and other industries to meet the diverse needs of customers.
We use high-quality materials for production to ensure that the products have excellent durability and stability. The products adopt advanced production processes and strict quality control standards to ensure that every product meets the highest standards. We provide customized product solutions to meet customers' unique equipment needs and application scenarios.
