What are the differences between mini ball valves and conventional ball valves

Mini ball valves and conventional ball valves have significant differences in many aspects. The following is a detailed comparison of the two: I. Dimensions and Weight Mini ball valve: Compact in size, light in weight, easy to carry and install. This gives it a great advantage in space-constrained situations. Conventional ball valves: They are relatively large in size and heavy in weight. Although it provides a larger traffic channel, it may not be very suitable in situations with limited space.

The principle and structure of hydraulic control valves

Hydraulic control valves are widely used devices in fluid control systems. The following is a detailed introduction to their principle and structure: I. Working Principle A hydraulic control valve is a type of valve that uses the pressure of the pipeline medium as the driving force to open, close and regulate. It uses the pressure of water in the pipeline network to control the opening, closing and opening degree of the valve. It is an auto

How to choose the appropriate solenoid valve based on actual needs?

Selecting the appropriate solenoid valve requires a comprehensive consideration of multiple key parameters and application scenarios. The following analysis is conducted from dimensions such as core parameters, medium characteristics, environmental conditions, and control requirements to help users precisely match their needs: I. Define the core parameters 1. Diameter and flow requirements Calculation method: Determine the diameter of the solenoid valve (DN value) based on the pipe diameter and the medium flow rate.

Why are sealing devices required for gate valves and globe valves?

Gate valves and globe valves are required to have upper sealing devices, mainly based on the following considerations: One. Prevention of medium leakage and protection of packing Prevent medium leakage: When gate valves and globe valves are in the closed state, the valve stems remain at rest. If there is no upper sealing device, the medium may seep upward along the gap between the valve stem and the valve body, causing the medium to leak out. The upper sealing device can effectively prevent the leakage of the medium and ensure the working performance and safety of the valve. Packing protection: The packing box is usually sealed with flexible mat

What are the differences between wafer-type butterfly valves and flanged butterfly valves?

Wafer-type butterfly valves and flanged butterfly valves are two common types of butterfly valves in industrial pipeline systems, and they have significant differences in structure, installation methods and application scenarios. The following are the specific differences between the two: 1. Structural features Wafer-type butterfly valve There are no flanges on both sides of the valve body. Usually, there are only a few guide bolt holes. It has a simple structure, small volume and light weight, and is composed of a few parts, such as the valve body, valve stem, butterfly plate and valve seat. Sealing method: Elastic sealing is usually adopted. The sealing ring can be em
