Category : V15 Gate Valves

Description

TVN V152 Rising Stem Gate Valve is a type of gate valve which is able to follow the opening/closing position by moving the stem up & down movement, is able to follow electronically the movement by adding a monitoring key, and full open position does not disrupt the flow. Rising Stem Gate Valve generates low head loss according to butterfly valves.
