What is a control valve?
valve noun \’valv\
any of numerous mechanical devices by which the flow of liquid, gas, or loose material in bulk may be started, stopped, or regulated by a movable part that opens, shuts, or partially obstructs one or more ports or passageways
control valve noun \kən′trōl ′valv\
a power operated device which modifies the fluid flow rate in a process control system; consists of a valve connected to an actuator mechanism that is capable of changing the position of a flow controlling element in the valve in response to a signal from the controlling system
Trimteck manufactures a comprehensive line of Optimux control valves – and a variety of actuators, positioners, severe service trims, and other accessories – that our applications engineers and representatives use to solve the most complex flow, pressure, and temperature control problems quickly and economically.

Control Valve Selection Information
The Reliability Cycle
Reliability of an industrial process is determined by the control of variables within the process i.e. Flow, Pressure, and Temperature. Since the final control elements – the fingers in the sauce – are control valves, proper valve performance is critical to the reliability of the process.
How do we classify Control Valves?
In order to simplify the selection and specification of a device with such a broad definition, control valves are traditionally classified according to one or more of the following factors:
- Non-return Throttling
- Final Control
- General Service
- Special Service
- Severe Service
Classifying Control Valves According to Service Application
General service valves are those designed for a majority of commonplace applications with lower pressure ratings
- Lower ANSI Class: 150 to 600
- Moderate Temperature: -50 to 650°F
- Noncorrosive fluids
- Minimal Pressure Drops
- No cavitation
- No flashing
- Carbon or Stainless Steel
- Interchangeable and common to a wide variety of applications
Special service valves are custom-engineered and designed for a single application due to any of the following:
- Higher pressures
- Demanding temperatures
- Corrosive fluids
- Moderate Pressure Drops
- Mild cavitation
- Special materials requirements
- Unique applications
Severe service valves are fitted with special features to handle extreme applications, such as high pressure drops that result in severe cavitation, flashing, choking, or high noise levels
- All pressures
- Extreme temperatures
- Severe Pressure Drops
- Custom-engineered trims
