Pressure Reducing and Temperature Control Valves

Of accuracy and repeatability for accurate temperature control and are equally accurate in mixing or diverting service over a wide flow range. The heavy duty rotor design provides tight temperature control without high maintenance requirements. Care must be taken to ensure that the entire length of the sensing bulb is immersed into the medium at the sensing location. Partial immersion of sensing bulb in the process fluid can result in faulty control. The sensing bulb is designed to be installed in either a horizontal or vertical or orientation . If the tip must be installed upwards, please specify when ordering, as a special bulb construction is required.
The temperature detecting element is responsible for sensing temperature signals and for sending either an electrical or mechanical signal to the actuator. If operating conditions are varied these valves allow flexible adjustment of the temperature range. Watch and listen to former sales manager Larry Brown discuss the advantages of using a steam regulator versus a steam valve.
Features a modulated signal output and a maximum set point of 400F. Products required for the design and installation of a complete control loop. This signal is then used by the actuator to act on the energy source, which determines the valve’s position. van điều khiển -acting type operates with either a flat diaphragm or convoluted bellows. Completely self-contained, it does not need an external sensing line downstream to operate. See how our high-performance mixing valve can protect end users from burns and accidental injuries in healthcare and public buildings.
You can chat with your supplier to make modifications or even get custom designs, and that’s what does for you. Powers provides flexiblity and economy with its #11 Regulator line of interchangeable sensing and control components. The line offers a selection of 29 thermal systems and up to 35 standard valve assemblies to meet a variety of specialty process needs. With these regulators, you can quickly replace the valve assembly in your supply line as your needs change or if a thermal system becomes damaged. Let us consider T1 as the temperature of the cold process fluid and T2 as the temperature of the hot process fluid. Mixing a cold and hot process fluid for controlling the temperature of the hot process fluid.
Beck electric actuators provide the necessary control and reliability that is required for many valve applications. The Group 11 quarter-turn valve actuator product line is often found on low to medium torque applications (20 lb-ft to 1,800 lb-ft). With expertise in valves and rich experience in the oil&gas, chemical industry, textile mills, power plants, and sugar mills. THINKTANK has become the premier manufacturer of next-generation precision control valves. In every power plant, the temperature control valve is a popular type of valve used. The heavy duty actuators are specially reinforced to provide vibration resistance.
Temperature control valves are distinguished based on the number of ports they have. It means the control valve with two ports is a 2-way valve and the one with three ports is a 3-way valve. Valves that work by detecting and regulating the temperature of the liquid inside are called thermostatic control valves. This temperature control valve is self-contained and requires no external power supply.
The only difference is that the control valve helps to maintain the temperature of a desired process at a specific level. It is often abbreviated as TCV – Temperature Control Valve – in most process drawings and P&IDs. Valves are tested for flow rate versus valve opening using a constant pressure drop to determine the valve’s inherent flow characteristic.
The entire housing is finished in a corrosion resistant, baked grey epoxy. Sensing bulb should be properly placed inside tank for best temperature consistency. An optional Thermowell may slightly reduce temperature sensitivity.
The Sleeve-Type is most commonly used for diverting applications; however, due to its design, it can also be used for mixing applications . It is also suitable for water or glycol type service, up to a maximum temperature of 300°F. A higher temperature O-ring for use with other fluids, such as oil, or for temperatures up to 410°F, is available. The W91/W94 Temperature Regulator is a fully self-contained unit requiring no external power source (i.e., compressed air or electricity).
