Industrial Valves:
Types, Uses, And Global Standards
Valves are vital components of all industrial piping systems.

1. Gate Valves

Standards:
API 600, ASME B16.34

Job:
Complete opening and closing - not suitable for organization (Throttling)

Treadmill:
Live - very low pressure

COMMON USES:

oil and gas lines

Water distribution systems

petrochemical plants.

Advantages:
good grip, simple design.

Defects:
slow to operate, corrosion when using in flow control.

2. Globe Valves

Criteria:
BS 1873, ASME B16.34

Job:
organize and adjust flow.

Treadmill:
S shaped - leads to significant pressure loss.

COMMON USES:

Boiler Feeding Systems

Steam & Cooling Circuits
Fuel systems

Advantages:
precision control, effective tightening

Disadvantages:
high pressure loss, heavier than other valves.

3. Ball Valves

Standards:
API 608, ISO 17292

Function:
Quick closure at 90° rotation angle.

Types:
floating ball or axle-loaded

COMMON USES:

Natural Gas Lines
Automated air systems
Hydrocarbonate lines

Advantages:
Integrated design, fast operation, excellent grip under high pressure

Defects:
not suitable for organization - risk of seat corrosion

4. Butterfly Valves

Standards:
API 609, ISO 5752

Function:
Quick opening/closing and limited organization

Designs:
Lug type, Wafer, Double/Triple displacement

COMMON USES:

Heating, ventilation and air conditioning (HVAC) systems

Water treatment plants

Fire protection systems

Advantages:
lightweight, economical, fast operation

Disadvantages:
less compulsion (unless there is displacement)

Criteria for selection of industrial valves

Based on API RP 615, ISA 75, and MSS-SP

🔸Middle type:
liquid, gas, abrasive liquid or corrosive liquid
🔸 Pressure and
temperature:
according to ASME pressure rating (Class 150 - 2500)
🔸 Operating method: manual, antenna, electric, hydraulic
🔸 Required Referee Score:
70-2 ANSI/FCI Standard
🔸 Installation direction and available space
🔸 Easy to maintain and access

The most important approved global standards:

API - American Oil Institute
ASME - American Society of Mechanical Engineers
ISO - International Organization for Standard Unification
MSS-SP - Manufacturers Standards Unification Society
DIN/EN - European and German standards
