Motorised Control Valve with AUMA Actuator

Motorised Control Valve

Flow control is the heart of any industry, and control valves play a pivotal role in maintaining the desired parameters of a process. At their core, control valves manage the rate of fluid flow by adjusting the size of the internal flow passage. Control valves utilise an actuator, triggered by a signal, to modulate the flow path and precisely regulate the fluid stream.

Control Valves help to:

  • Regulate Flow: Flow control valves ensure that every process receives the precise amount of flow it needs.
  • Manage Pressure: Pressure Control Valves ensure that all downstream equipment operates at the right pressures and keep the pressure in check, safeguarding equipment and personnel.
  • Govern Temperature: Precise flow regulation translates to controlled temperature fluctuations. Temperature Control Valves prevent overheating in a manufacturing process or maintain the delicate balance in a chemical reactor.
  • Maintain Level: From ensuring consistent liquid levels in storage tanks to regulating the water level in a boiler, Level Control Valves keep liquids and gases flowing at the right depth.

Applications

100% & 30% Feed Water Control Valve:

Feed control valves are essential for ensuring a steady and reliable supply of feedwater to the boiler. The 100% feed control valve is used during high-load periods, whereas the 30% valve is used at partial-loads offering finer control over the feed water flow.

Start-up Vent Valve:

The Start-up Vent Valve in boilers is a severe service application that helps in venting the steam from the system during the plant start-up phase.

Attemperator Control Valve:

The Attemperator Control Valve in boilers plays a critical role in regulating the temperature of the final superheated steam by injecting water into it.

Auto Gland Seal Control Valve:

An Auto Gland Seal Control Valve automatically regulates the pressure of sealing steam around a turbine shaft, preventing air leaks and minimising steam loss. It essentially maintains a balanced “barrier” preventing external air from entering the turbine while allowing controlled leakage of sealing steam outwards.

Condensate Pump Recirculation Valve:

Condensate Pump Recirculation Valve Maintains optimal flow and prevents cavitation by recirculating excess condensate back to the suction of the condensate pump.

Exhaust Casing Drain Valve:

The Exhaust Casing Drain Valve drains away condensate from the turbine & maintains pressure balance.

Boiler Feed Pump Recirculation Valve:

The boiler feed pump recirculation valve regulates the bypass flow from the pump outlet back to the deaerator. This bypass flow prevents overheating and cavitation of the pump.

Deaerator Level & Pressure Control Valve:

The Deaerator Level & Pressure Control Valve maintains optimal water levels and pressure within the deaerator, ensuring efficient removal of dissolved gases such as oxygen from the boiler system.

Soot Blower Control Valve:

A soot blower control valve regulates the release of steam to remove accumulated soot and ash from the interior walls of the boiler heating surfaces.

Hotwell Level Control Valve:

The Hotwell Level Control Valve in a steam turbine system helps to manage the water level in the condensate hotwell. This tank collects condensed steam from the turbine exhaust, and maintaining its level is crucial for efficient and safe operation.

Exhaust Hood Spray Valve:

The Exhaust Hood Spray Valve sprays water into the turbine exhaust hood, thereby preventing overheating & optimising performance.

Vacuum Breaker Valve:

The Vacuum Breaker Valve acts as a safety valve for the turbine’s vacuum, letting in air to prevent implosion due to sudden loss of vacuum in the condenser & for quick shutdown during emergencies.
