q71f wafer ball valve product overview

the q71f wafer ball valve produced and sold by wocivalve (shanghai) co., ltd. refers to the characteristics of italian products. compared with ordinary ball valves, it has significant advantages such as short structural length, light weight, convenient installation and material saving. the jacketed ball valve has good thermal insulation effect. in addition, the valve seat adopts elastic sealing structure, which has reliable sealing and easy opening and closing. it is equipped with fire-resistant structure, which can still operate reliably and have good sealing in case of fire. according to the needs of users, anti-static structure can be set. a 90 ° switch positioning piece with hole is set, which can be locked as required to prevent misoperation.

application of q71f wafer ball valve
