Valves for Industrial Processes

The selection of valves in industrial processes is based on the environment: steam, hot oil, chemical liquid, or compressed air — each has different temperature, pressure, and material requirements. An incorrectly selected order point (tightness) or unsuitable sealing material can lead to leakage and process downtime.

Typical Requirements

Thermal Oil Lines — 2 and 3-way motorized thermal oil valves for high temperatures; sealing and body material are selected according to working temperature.
Steam and Hot Water — design considering expansion and water hammer, protection of the pump with a check valve.
Automation — butterfly valves with electric or pneumatic actuators, sliding gates, and solenoid valves allow for PLC control of the process.
Actuator Selection — the required torque, opening-closing time, and whether on/off or modulation mode must be predetermined.

Pneumatic actuators are preferred for fast and explosion-risk zones, while electric actuators are favored for precise positioning and areas without air lines.
