Technical Specifications

1. Size Range:

Standard sizes typically range from 1/2" to 36" (or larger depending on design).

2. Pressure Ratings:

ANSI Class ratings (150, 300, 600, 900, 1500, 2500).

DIN ratings (PN10, PN16, PN25, PN40, etc.).

3. Flow Coefficient (Cv):

A measure of the flow capacity of the valve, indicating how much flow (in gallons per minute) can pass through the valve at a specific pressure drop.

4. Temperature Range:

Generally from -50°F to 800°F (-45°C to 427°C), depending on materials and design.

Control Modes:

• Proportional Control: Adjusts flow based on the deviation from a setpoint.

• Integral Control: Corrects the steady-state error by integrating the error over time.

• Derivative Control: Anticipates future errors based on the rate of change.

Applications and Use Cases

• Process Control: Used in various industries to regulate flow, pressure, temperature, and level.

• HVAC Systems: Control air flow and temperature in heating and cooling systems.

• Water Treatment: Control the flow of chemicals and water in treatment plants.

• Oil & Gas: Regulate the flow of crude oil, natural gas, and refined products.

Standards and Certifications

• Manufacturing Standards: Comply with ANSI/ISA, ASME, API, and ISO for design and testing.

• Material Certifications: Compliance with ASTM and other relevant material standards.
