DK55-PVF Electric PVC/UPVC Double Union Flange Ball Valve - Corrosion Resistant & Easy Service
The DK55-PVF Electric Ball Valve is a lightweight, high-performance solution that offers the ultimate in installation flexibility and corrosion resistance. Constructed from durable PVC/UPVC plastic, it is designed to handle acids, alkalis, and saline solutions. This valve features a unique Double Union Flange design, which combines the secure, standardized mounting of a flange connection with the convenient inline maintenance of a true union—allowing the valve body to be quickly removed for service without disturbing the pipe flange connection, significantly reducing downtime in chemical and water treatment applications.
Features
An automated, corrosion-resistant PVC/UPVC ball valve featuring a specialized double union flange connection for both secure industrial mounting and fast, convenient inline maintenance.
✅Hybrid Double Union Flange Connection: The unique structure allows the valve to be securely mounted into flanged industrial pipe systems while simultaneously utilizing union nuts for quick, tool-free disassembly and reassembly of the valve body for service.
✅Superior UPVC Chemical Resistance: Constructed from UPVC, the valve is immune to rust and highly resistant to most acids, alkalis, and aggressive chemicals, offering a long service life and a cost-effective alternative to metallic alloy valves.
✅Quick Inline Maintenance: The Double Union design ensures that the central valve body can be easily removed for seal or seat replacement simply by loosening the union nuts, greatly reducing maintenance time and labor costs.
✅Reliable Electric Automation : Equipped with the electric actuator, the valve provides reliable remote on/off control with low operating torque, making it highly efficient for automated dosing and switching processes.
✅Hygienic and Lightweight: The non-toxic nature of the plastic material makes it suitable for purified water systems. Its lightweight construction also reduces the stress and weight load on the flange and pipeline supports.
