Eccentric Hemisphere Valve--Detailed Introduction

DVQ eccentric hemispherical valve, with a hemispherical core, is an ideal product design. When the valve is opened or closed, it can use the eccentric effect to prevent direct friction between the sealing surface and the spherical surface, which can effectively improve the service life of the valve and prevent the valve from opening but not closing or closing but not opening under high temperature.
