I. Product Overview

The hydraulic gate valve is equipped with a manual operation device, which can remotely control the opening or closing of the valve by the vertical linear movement of the valve plate. The valve body is made of cast steel and stainless steel, with a nominal diameter range of DN50 to DN1200mm, a maximum operating temperature of 425°C, and a nominal pressure in the range of 1.0 to 1.6MPa. This valve is widely used in various fields such as chemicals, coal, sugar production, wastewater treatment, and papermaking, and it performs exceptionally well in pipeline regulation and throttling operations in the papermaking industry.

II. Product Features

1. Diverse structural designsAvailable in two types based on diameter differences: dark rod (DN50～900mm) and clear rod (DN50～900mm). Designed with a full circular DC channel to prevent material sedimentation and blockages. The blade at the bottom is shaped like a knife edge, capable of cutting soft materials such as fibers, pulp, and wood pulp, while ensuring smooth opening and closing of the valve. A hard polytetrafluoroethylene scraper is installed at the top of the blade, effectively blocking abrasive materials like dust and sand from entering the packing box, significantly extending the blade's lifespan. The valve plate is made of stainless steel and polished to achieve optimal sealing. The overall design is compact, with minimal space requirement and light weight. It is affordable, easy to install, features comprehensive wear-resistant and anti-blocking measures, is easy to maintain, and has a long service life. It also allows for the selection of a drive unit.

2. High-quality material craftedThe valve bodies and stuffing boxes are both precision cast. The valve bodies are integrally cast with flanges, and materials can be selected according to customer requirements, including 304, 316, 316L, WCB, 2Cr13, etc. The sealing rings are made of PTFE reinforced polytetrafluoroethylene, offering corrosion resistance, wear resistance, and non-adhesive properties.

3. Stable valve plate supportThe valve plate features 5 support points, ensuring excellent self-alignment performance. When the valve is closed and subjected to back pressure, the valve plate does not shift, guaranteeing stable operation of the valve.

4. Comprehensive driver configurationsAvailable with adjustable handwheels, manual zipper, spur gear drive, bevel gear drive, pneumatic, and electric drive options, catering to various operating conditions and requirements.

5. Flexible channel designInternally, it can be formed into V-shaped, triangular, and pentagonal channels. The V-shaped gate is suitable for regulating and controlling, offering a diverse range of choices for different medium flow and control requirements.

6. A variety of connection and sealing methodsThe connection types include clamping and flanged lug; the sealing options feature metal-to-metal hard seal, metal-to-polyurethane, and reinforced polytetrafluoroethylene soft seal. Users can select the most suitable connection and sealing method based on their actual operating conditions.

7. Wide media compatibilitySuitable for a variety of complex media such as gold ore powder, tailings, pulp, fiber, dust, chemical treatment wastewater, sedimentation tanks, ore sand, slag, coal sludge, asphalt, material silo outlets, fruits, grains, cement slurry, and slaughterhouse effluent.

8. Broad temperature and pressure rangeSoft-sealed (PTFE) operating temperature: -40℃ to 180℃; carbon steel: -29℃ to 425℃; stainless steel: -40℃ to 600℃; chrome-molybdenum-vanadium steel ≤550℃. The working pressure range is 0.6 to 1.6 MPa, capable of adapting to different temperature and pressure conditions in the working environment.

9. Standard connection form: Utilizes both flange and clamp connections for easy installation and compatibility with various pipeline systems.
