Y-type plastic stop valve is a valve used to control the flow of fluid in pipeline systems. It has a unique Y-type design that can reduce fluid resistance and pressure loss. It is suitable for the transportation of various chemical media and is widely used in chemical, environmental protection, pharmaceutical, water treatment and other fields. The valve is opened and closed by rotating the handle, and a conical or flat sealing structure is used inside to ensure good sealing performance and a long service life. The design of the Y-type structure not only reduces the turbulence of the fluid, but also reduces the wear inside the valve. It is particularly suitable for systems that require lower pressure drop and long-term stable operation. The Y-type plastic stop valve has the characteristics of light weight, easy installation, and strong chemical resistance. It is particularly suitable for use in corrosive or special environments.
