Hydraulic ball valve

Product Name: Q741F Hydraulic Stainless Steel Ball Valve

Product Introduction:

Hydraulic ball valveQ741F Hydraulic Stainless Steel Ball Valve/Explosion proof Hydraulic Flange Ball Valve/Hydraulic Flange Ball Valve/Hydraulic Carbon Steel Ball Valve/Precision Hydraulic Flange Ball ValveSuitable for use as a starting and closing device on gathering and transportation pipelines for media such as water, oil, natural gas, drilling fluids, etc. The hydraulic flange ball valve consists of two main parts: the hydraulic device and the ball valve. By relying on a hydraulic device to rotate the valve stem and drive the ball to rotate, the opening and closing function is achieved.

Product advantages:

Hydraulic valves are more convenient for users to operate, lightweight, and can be operated remotely through automation. This has expanded the range of applications for half globe valves, especially in harsh environments where manual operation or normally open action is not convenient. When paired with automated computer operation, the double eccentric half globe valve is equipped with a hydraulic actuator, which opens up new ideas. This valve has all the advantages of a double eccentric hemispherical valve, such as low opening force, the ability to remove scaling obstacles when closed, and good sealing performance. It is wear-resistant. Corrosion resistant material. Hydraulic valves are widely used in two-phase mixed media such as water, steam, sewage, papermaking, petrochemicals, natural gas, solutions, and slurries, as well as ideal equipment for conveying dusty gases, granular fluids, and powder solid media. Using hydraulic operation, it is more convenient for management automation, remote control, and is equipped with hydraulic signal devices, which can be used for automated operation and centralized control.

Introduction to SG hydraulic actuator:

Hydraulic actuator is a new type of hydraulic actuator. The SG series actuators are designed and optimized using the 3D modeling software Solidworks. Compared with similar products on the market, it has the characteristics of exquisite and beautiful appearance, compact and reasonable structure, sturdy and durable, high output torque, and long service life. SG series actuators can be used as actuators for valves such as ball valves, butterfly valves, plug valves, or other 1/4 turn devices. Supporting components such as hydraulic solenoid valves, flow control valves, and limit switches can achieve local/remote intelligent control of valves such as ball valves, butterfly valves, plug valves, or other 1/4 turn devices. SG series hydraulic actuators are widely used in petroleum, chemical, power, energy, shipbuilding, metallurgy, building materials, papermaking, and boiler equipment.

Product features:

1. Supports single acting and double acting configurations.

2. Based on the gear rack design, the structure is simple and reliable, the volume is small, the action is smooth, and the output torque is large.

3. The gear rack is made of 45 # steel, which can withstand higher working pressure and output greater torque.

4. The hydraulic cylinder uses 45 # seamless steel pipe, which has good comprehensive mechanical properties; Smooth inner surface, low friction coefficient, ensuring longer service life.

5. The back of the actuator is designed with two adjustment bolts, making stroke adjustment more convenient. Support bidirectional travel adjustment, with an adjustment range of ± 5 °.

6. The bottom connection of the actuator complies with the ISO5211 standard. Make the product more versatile and interchangeable.

7. The top connection of the actuator complies with NAMUR standards. Support the installation of standard valve position indicators and limit switches (HA32 requires special installation brackets).

Typical applications:

Automation of ball valves, butterfly valves, plug valves, and other 1/4 turn devices.

Working conditions:

1. Hydraulic oil: Use non corrosive anti-wear hydraulic oil; Medium viscosity in motion.

2. Rated pressure: Design pressure of 20MPa; The maximum operating pressure is 16MPa.

3. Applicable temperature: -20~+80 ° C

4. Vibration resistance: suitable for environments without strong vibrations

5. Lubrication: Using self-lubricating bearings, no lubricant needs to be added under normal working conditions.

6. Installation: Suitable for indoor and outdoor installation and use.

7. Selection and marking: Reasonably select according to specific working conditions; The relevant parameters will be marked on the product nameplate.

Attachment support:

1. Manual mechanism: Supports clutch manual mechanism or manual pump

2. Limit switch box: It can accommodate various limit switches or position transmitters.

3. Hydraulic solenoid valves, electro-hydraulic servo systems, accumulators, etc. are used to operate or control valves.
