Product Features:
·O ball valves are usually used as cut-off valves.
·Its flow is simple and fully forms straight channel when full open,with minimum pressure loss.
·Specially, it's suitable for high viscosity, suspension occasions, such as pulp fluid.
·Reliable sealing, very small leakage. Soft seal ball valves can reach bubble level seal.
·Using SKJ Fast Speed quarter turn electric actuator, fast on/off speed, rated travel time is 3s, 6, used for emergency cutoff.
