Woke Zhihe Valve Co., Ltd. is a professional manufacturer of pneumatic pinch valves and pinch valve inner bushings. The key technology of the pneumatic pinch valve is the rubber inner bushing, but it has long been in foreign companies. Domestic enterprises have no successful cases in the development and production of this product, subject to the price and technology monopoly caused by foreign-funded enterprises.

In 2013, the company set up a rubber laboratory, hose fatigue, hose life simulation test center, a series of equipment for hose production, and hired a doctor of rubber polymer to assist in research and development. After 4 years of research and development, the company's pinch valve has reached the import quality (long life, good resilience, wear resistance, food hygiene), of which DN40-DN65 is more than 600,000 times and DN80-200 is up to 300,000 times. Above, it has been successfully installed in rail transit (China CRRC) and various industries. It is the best manufacturer of pinch valves at home and abroad, and has received consistent praise from customers.
