To cooperate with our valve ball products, we developed valve seat products together with our associated suppliers to enrich our product range, also for furnish full package of supports to our customers. Guoyang Valve (GY Balls) can supply valve seat size range DN50~DN1200mm (2”~48”), including the metallic, resilient, metal-sealed, etc.
Beside of the single metallic or resilient type, the valve seats mostly ordered together with the valve balls, such as the PMSS (Primary Metal and Secondary Soft) seat and Metal-to-Metal seat are available to satisfy special working conditions.
