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 BSQ series ON-OFF electric actuator, with large output torque, simple operation, economical and practical, but shoudl avoid frequent operation.
