The balanced valve body independently developed and produced by our company is widely used in HVAC with actuators, controllers and sensors from Siemens, Honeywell and other brands
Industrial automatic control systems such as hot and cold water systems, humidification and ventilation systems, differential pressure bypass systems, urban heating systems, and metallurgical environmental protection systems can achieve precise control of parameters such as flow, pressure, differential pressure, temperature, and humidity. It has the advantages of beautiful appearance design, convenient installation and use, high adjustment accuracy and long service life.
The company now has a square meter production base and product testing center and uses advanced domestic and foreign special CNC machine tool processing equipment. Every process from the finishing of parts to the assembly of the valve body and the pressure test before leaving the factory is completed in strict accordance with the company's standard procedures. The regulating valve produced has passed the special equipment manufacturing license (pressure pipeline component - regulating valve) issued by the Provincial Bureau of Quality and Technical Supervision.

, product features
◆Precision casting (resin sand)
◆All-metal connection valve seat ensures service life
◆Conforms to national standards for steel pipe flanges
◆Complies with the special equipment manufacturing license of the China Bureau of Quality and Technical Supervision
◆The two-way design is a pressure-balanced design with smaller driving thrust and saves costs
◆The use of pressure-balanced type ensures that under low force High shut-off capacity
Switching and closing freely under high pressure difference
◆The seals are imported products that are tightly sealed, resistant to high temperatures and prevent cavitation.
