Temperature Control Valves
Temperature control covers a host of applications from feed tank temperature control via steam injection to secondary process temperature control via plate heat exchangers. Closed loop processes are finely calibrated to ensure the process is responsive to changing conditions. Valveforce’s experiences engineers will set up your PID loop on site to ensure that your set temperatures are achieved in a stable and reliable way. We also cover smaller processes where self-acting temperature control is suitable.
Pneumatic Control Valves for Temperature Control
- The first choice for temperature control for larger processes
- Instantaneous response via pneumatic control
- Ideal for processes such as DHW heating
- Steam injection
- Fitted with electro pneumatic positioners tailored to meet requirements such as Profibus protocols and Atex environments
Electric Control Valves for Temperature Control
- For applications where electric actuation is necessary we have fast acting electric actuators
- Suitable for processes such as DHW heating
- Our actuation speeds ensure processes won’t overheat
Self-Acting Thermostatic Valves
Feeling the Way to Better Temperature Control
The thermostatic temperature controller, which consists of a thermostat and a temperature control valve, is used for controlling temperatures in central heating, district heating systems, industrial plants or marine systems. It can be used for the control of cold or hot water, steam or oil, in heating or cooling systems.
A thermostat consists of a sensor and a capillary tube filled with liquid and an adjusting cylinder. The thermostat is self-acting and based on the principle of liquid expansion. It has a sturdy design and operates with a large closing force. The adjusting cylinder of the thermostat is set at the required temperature for the heated medium in °C.
The temperature control is carried out by the thermostatically controlled temperature control valve reducing or increasing the flow of the heating
(or cooling) medium.
If the temperature of the medium to be heated is above the required level, the sensor liquid expands causing the piston of the thermostat to act upon the automatic temperature control valve, reducing the flow of the heating medium. If the temperature of the medium to be heated is below the required level, the temperature of the sensor liquid falls, reducing the volume of the liquid so that the piston allows the automatic temperature control valve to open under its internal spring, thus increasing the flow of the heating medium.
- Our range is suitable for steam, water and thermal oil processes
- Direct-acting valves for heating applications
- Reverse-acting valves for cooling processes
- Bellows an piston balanced valves allow for larger self-acting valves with shut off against higher pressure
- 3-way valves for diverting/ mixing
- Quick acting via fluid expansion in the valve thermostat
- Low demand DHW heating
- Low demand steam injection
- Blowdown vessel cooling
