In the fields of central air conditioning, heating, water treatment, industrial processing, etc., accurate and reliable control of fluids (cold and hot water, non-corrosive liquids, 50% ethylene glycol, deionized water, etc.) is essential. As a key component, electric valves play a vital role. They are driven by electric energy to achieve remote control and automatic adjustment to ensure the stability and efficiency of the water system. The DDF-Z, DDF-S, DDF-Q, DDF-B, and DDF-C series electric seat valves in the Hengsen electric valve series are high-performance valve solutions designed and manufactured to meet this core demand.
Hengsen Electric Seat Valve Series Technical Commitment
1. Optional valve body materials: cast copper/stainless steel/ductile iron
2. Applicable media: hot and cold water, non-corrosive liquids, 50% ethylene glycol, deionized water
3. Diameter coverage: DN15~DN200
4. Customization supported: R&D and customization based on customer needs
Core advantages and features
1. Excellent precision control:
The unique valve core and valve seat design provides excellent flow characteristics (equal percentage, linear), ensuring accurate flow regulation within the entire stroke range.
2. Excellent reliability:
The valve body flows directly through the water, does not block slag, and the KVS value is much larger than that of ordinary two-way valves; the closing pressure difference is large and the closing is tight; the valve opens flexibly, which can effectively prevent water hammer; the sturdy and durable valve body structure can withstand high working pressure and temperature range, has a long service life and low maintenance cost.
3. Stable electric actuator:
Equipped with Hengsen's self-developed electric actuator, it ensures that the valve can be reliably opened and closed or accurately adjusted under various working conditions; maintenance-free design, simple and quick installation; the actuator has safety functions such as travel limit and fault alarm to ensure the safe operation of the equipment; it provides a variety of control signal input and feedback signal output options, strong compatibility, and easy to integrate into various automation systems.
