Chinese Electric Flexible Soft-seal Gate Valve (Model: Z945X-16Q) for Municipal Sewage - Remote Control Flanged Valve
Product Description
Z945X-16Q Electric Flexible Seal Gate Valve: Intelligent Sealing Control Solution for Municipal Sewage Systems
The Z945X-16Q electric flanged gate valve is a remote-adjustable valve specially designed for municipal sewage treatment scenarios. It integrates flexible seal technology with an intelligent electric drive system. With the structural strength of ductile iron and the zero-leakage advantage of rubber seals, it is suitable for fluid control requirements in multiple stages such as sewage lift stations, biochemical treatment ponds, and pipe network diversion. Through remote automated regulation, it significantly improves the efficiency and operational safety of sewage treatment.
Core Performance and Structural Advantages
1. Flexible Seal Technology, Zero Leakage of Sewage
It adopts an imported EPDM rubber flexible valve seat and a streamlined gate plate combination. By leveraging the "metal framework + soft sealing layer" structure, the soft material's elastic deformation fills the tiny gaps on the sealing surfaces, creating a pressure self-compensation sealing effect - the higher the system pressure, the stronger the contact pressure between the gate plate and the valve seat, achieving a sealing grade up to international A-level standard, with leakage volume ≤ 1×10⁻⁶ml/s after 10 million opening and closing cycles. The flat-bottom valve seat design is flush with the pipe inner wall, reducing sediment and flocculent deposits in the sewage and avoiding scratches on the sealing surface caused by impurities, perfectly adapting to the complex conditions of municipal sewage containing impurities.
2. Ductile Iron Valve Body, Dual Protection against Corrosion and Pressure
The valve body is cast from high-strength ductile iron with a graphite ballization rate of over 90%, combining the corrosion resistance of cast iron with the toughness of steel. It weighs 20%-30% less than traditional gate valves while being able to withstand a nominal pressure of 1.6MPa. The surface is coated with a 250μm thick epoxy resin layer, forming a dense protective layer, with a salt spray test duration exceeding 1000 hours, capable of resisting long-term corrosion from chlorine ions and sulfides in the sewage, and extending the service life by more than 3 times compared to ordinary carbon steel valves. The flange connection end faces are precisely processed in accordance with ISO 7005 standards, combined with a dual-sealing structure, ensuring a reliable connection with the municipal pipeline system.
3. Intelligent Electric Drive, Support for Remote Precise Adjustment
Equipped with a high-precision servo electric actuator, the opening and closing torque can reach 5000N・m. It supports 4-20mA analog signals or Modbus bus control, enabling 0-100% stepless adjustment, precisely matching the flow requirements of each stage of sewage treatment. It is equipped with an intelligent control module, with a rotation angle control accuracy of 0.5°. It can be connected to the municipal smart water management platform for remote monitoring, automatic opening and closing, and fault alarm, eliminating the need for on-site manual operation, reducing operational risks in harsh environments. Some models have explosion-proof rating ExdⅡBT4, suitable for flammable and explosive sewage gas scenarios.
4. Hidden Lever Design, Easier Installation and Maintenance
The lever adopts a hidden lever structure, with the valve stem threads completely hidden inside the valve body, avoiding corrosion and wear caused by direct contact with sewage, while saving 40% more installation space than the exposed lever gate valve. The valve stem is made of 316L stainless steel and undergoes surface nitriding treatment. An O-ring, flexible graphite packing, and dust-proof lip edge are set up for triple sealing between the valve stem and the valve cover, ensuring long-term opening and closing flexibility. The sealing components are designed in a modular manner, with only the rubber valve seat needing to be replaced to restore performance, without the need for overall valve disassembly, reducing maintenance time to 1-2 hours, significantly reducing pipeline downtime losses. Applicable scenarios
• Municipal sewage treatment: Pump station inlet and outlet control, water distribution adjustment in biochemical reaction tanks, pipeline cutting for sludge transportation, pipe interception valves, etc.;
• Water supply system: Water distribution network for water treatment plants, secondary water supply equipment, flow regulation for wastewater reuse systems;
• Industrial wastewater: Flow on/off control and regulation for low-concentration corrosive wastewater treatment in industries such as food and printing and dyeing.
Manufactured in accordance with API 598 sealing test, ISO 5208 fire safety certification and GB/T 13927 standards, the Z945X-16Q electric elastic flexible-sealed gate valve, with its core advantages of "zero leakage, strong corrosion resistance, and intelligent regulation", has become a key equipment for the stable operation of municipal sewage treatment systems.
