Chinese Double-acting Pneumatic & Manual Integrated Gate Valve - Cast Steel/Stainless Steel Flanged Connection, On-off Type
Product Description
【Product Name】 Handheld Integrated Electric Soft-Sealed Flange Gate Valve (Remote Control / On/Off Type - Sewage Specialized) [Core Positioning] An efficient fluid control device that integrates manual emergency operation with electric intelligent control, specifically designed for complex medium transportation scenarios such as sewage. With excellent sealing performance and flexible operability, it is suitable for municipal drainage, sewage treatment, environmental engineering, and other fields' pipeline systems for on-off and flow regulation needs.
I. Core Structure and Performance Advantages
Dual-operation mode actuator: Equipped with a handheld integrated actuator. In the electric mode, it can receive remote control signals and drive the valve stem movement through a high-precision motor and reducer, achieving automatic opening and closing of the valve and flow regulation; in case of power failure or need for on-site operation, it can switch to the manual mode by rotating the handle to complete the control, providing dual guarantees to ensure uninterrupted operation.
High-quality soft-sealed system: The gate plate adopts an overall rubber coating process, using wear-resistant and corrosion-resistant rubber or polytetrafluoroethylene materials, and is closely attached to the valve seat to form a reliable sealing structure, effectively preventing sewage leakage, while the bottom of the valve adopts a flat design to avoid debris accumulation and reduce maintenance costs.
Dual-pull rod optional design: Provides two types of structures for selection: exposed rod type and concealed rod type.
Exposed rod type: The valve rod rises and falls synchronously with the gate plate, and the valve rod position can be used to intuitively determine the valve's opening and closing status. The transmission thread is located outside the valve body, facilitating lubrication and maintenance, suitable for scenarios with ample installation space;
Concealed rod type: The valve rod only rotates, while the gate plate rises and falls inside the valve body. The overall height is compact, and the valve rod thread is protected by the valve body, reducing external corrosion, suitable for underground installation or space-constrained conditions.
Strongly compatible flange connection: Uses standard flange connection method, facilitating connection with the pipeline system. The valve body is made of high-quality cast steel or stainless steel, and the inner wall is treated with anti-corrosion treatment, capable of withstanding impurities and corrosive components in sewage, extending service life.
II. Application Scenarios and Core Parameters
- Applicable media: Domestic sewage, industrial wastewater, sewage mixtures, etc.;
- Control mode: Remote electric control (supporting integration with automation systems) + on-site manual operation;
- Function type: Equipped with both on-off and flow regulation functions, meeting the fluid control needs of different working conditions;
- Compatible pressure: Nominal pressure can reach PN10-PN16, working temperature ≤ 100℃, suitable for most sewage pipeline operating parameters.
III. Safety and Maintenance Characteristics
Reliable protection design: The valve body is overall treated with non-toxic epoxy resin spraying, with an internal and external anti-corrosion coating thickness of 250μm, effectively resisting sewage corrosion and environmental erosion; the actuator has good waterproof and dustproof performance, suitable for harsh working environments.
Convenient maintenance structure: Uses a press cover mother self-tightening seal, the sealing wear parts can be replaced separately, without disassembling the entire valve, regular inspection of the sealing performance and motor status of the actuator can ensure stable operation, reducing maintenance difficulty.
