Understand The Different Types of Valves

Determine Fluid Flow & Pressure

It is important to accurately determine the flow and pressure range of the liquid to be handled, which will directly determine whether the selected valve type is suitable. Among them, "flow rate" refers to the rate of liquid passing through the valve per unit time; The "pressure" determines the amount of load that the valve is subjected to during operation. These parameters will help you confirm the size and material required to ensure that the selected valve will meet the expected operating conditions and withstand the appropriate pressure.

Determine The Nature of The Fluid

To help you efficiently complete pipeline valve selection, we have sorted out the following key steps and required information to ensure that the selected valve delivers optimal performance in your application scenario:

There Are Two Characteristics of Valves

Usage Characteristics

It determines the main performance and scope of use of the valve.

The Valve Usage Characteristics Include:

Valve Driving Mode

manual, electric, pneumatic, hydraulic
Main Parts of The Valve

valve body, valve cover, valve stem, valve disc, sealing surface materials
Product Types

gate valves, globe valves, butterfly valves, ball valves, etc.
Types of Valves

closed-circuit valves, regulating valves, safety valves, etc.

structural characteristics

It determines some structural characteristics of the valve installation, repair, maintenance and other methods.

Structural Features Include:

Valve Stem Structure

rotating stem, lifting stem, etc.
Form of Sealing Surface

insert ring, threaded ring, overlay welding, spray welding, valve body itself
Pipe Connection Forms

flange connection, threaded connection, clamp connection, external thread connection, welded end connection, etc.
Valve Structure

valve body length and overall height

Steps to Select a Valve

START

Clarify Fluid Properties

Provide fluid characteristics such as temperature range, pressure range, viscosity, and corrosivity. For instance, high-temperature or corrosive media require special materials (e.g., high-temperature resistant alloys or linings). These parameters directly influence the weather resistance and sealing design of the valve material.

01
Determine Flow and Pressure Requirements

Specify the fluid flow rate per unit time (e.g., m³/h) and operating pressure range. This determines the valve's nominal diameter (DN) and pressure rating (e.g., PN16), ensuring the valve can withstand actual loads and match the pipeline system.

02
Select Valve Type
1. Match the appropriate valve from common types based on fluid and operational requirements:
  Providing a description of your application scenario (e.g., chemical industry, water treatment) can facilitate precise recommendations.
03
Define Operational Requirements
Specify the operation mode (manual/automatic) and key performance indicators:
- Automation Needs: Control accuracy requirements for electric or pneumatic actuators.
- Performance Metrics: Opening/closing speed, sealing class (e.g., zero leakage), and long-term reliability. For example, scenarios involving frequent operation require a highly durable design.
04
Evaluate Installation Environment
Describe the on-site conditions:
- Space Constraints: Compact valves (e.g., butterfly valves) are suitable for narrow areas.
- Environmental Factors: Extreme temperatures, vibrations, or corrosive surroundings require shock-resistant and anti-corrosive treatment.
Providing details of the installation location (e.g., indoor/outdoor, adjacent equipment) can optimize the selection.
05
Summary of Required Information

Fluid properties (temperature, pressure, corrosivity)
Flow and pressure parameters
Valve function requirements (on/off / regulation)
Operation mode and automation level
Installation environment description (space, climate, surrounding media)

06
Select The Valve Type

Select the valve type—stop valve, regulating valve, safety valve, etc.

07
Purpose & Conditions

Determine the role of the valve in the equipment or device. Determine its working conditions, such as the media it controls, operating pressure and temperature.
