DN1200 Cone valve ready for shipment
The DN1200 PN16 large-diameter cone valve has completed full pressure tests including hydrostatic strength test and tightness test, together with on-site opening & closing operation commissioning. It has successfully passed factory acceptance inspection and is ready for delivery to overseas hydraulic engineering projects.

Cone valves are preferred equipment for water release, energy dissipation and reservoir emptying applications with remarkable core advantages. The valve features a smooth flow passage. Water flows out through the annular gap between the conical sleeve and valve seat to achieve outstanding energy dissipation performance, which greatly reduces the impact force of high-speed water flow and protects downstream hydraulic structures. It supports a wide flow regulating range and enables stepless continuous flow adjustment from zero to full capacity with stable control accuracy. The compact short structure saves installation space. When equipped with an external flow deflector hood, it further optimizes the water discharge pattern and restrains water atomization and riverbed scouring. This unit adopts base material complying with BS10025.2 standard, and the sealing surface is equipped with **SS304 weld overlays**, delivering strong resistance against corrosion and water abrasion to support long-term continuous hydraulic service.

The client selects cone valves mainly for operational safety and lower life-cycle maintenance cost. Conventional gate valves and butterfly valves are vulnerable to cavitation and vibration under large differential pressure discharge conditions. High-speed water flow will quickly shorten valve service life and damage downstream infrastructure. By adopting the annular outflow energy dissipation principle, cone valves dissipate water energy outside the valve body, which drastically mitigates cavitation risks, lowers vibration and operational noise, and cuts long-term maintenance workload.

This type of valve is widely deployed for dam flood release & reservoir emptying, surge regulation of reservoirs, water diversion projects, overflow discharge of wastewater treatment plants, pressure relief for pumping stations and other scenarios. It serves large-scale B-side projects in hydropower and municipal water sectors. This DN1200 large-size cone valve is fitted with an external flow guide cover to stabilize the water outflow direction and minimize water mist diffusion, meeting strict technical requirements for reservoir emptying and flood discharge of large overseas water conservancy projects. The valve has gone through full workshop pressure testing and cyclic opening-closing commissioning. All performance indicators comply with engineering specifications to guarantee safe and stable long-term operation, delivering reliable fluid control solutions for global hydraulic projects.
