Water treatment plants use butterfly valves across intake, process, backwash and distribution systems. Each location can impose different coating, actuator and control requirements.
Raw water
Solids, debris and biological activity influence seat and disc selection.
Filter service
Frequent cycling and modulating duty require attention to torque and actuator duty.
Treated water
Potable-water material approvals and hygienic coating systems may be required.
Automation
Coordinate position feedback, interlocks, fail action and travel time with the plant control philosophy.
Information to include with an enquiry
Provide nominal size, pressure rating, medium, temperature, connection standard, materials, operating method, required testing and project documentation. Greysen will review the duty and confirm the final configuration in the approved data sheet.
