Valves and actuators HVAC Products Siemens USA

While they are more durable against regular wear and tear than a solenoid valve, it is still something to take into consideration. Spirax Sarco’s ball valves coupled with pneumatic actuators provide the ideal solution for your isolation valve needs. An electric actuator converts energy into torque that moves or controls the mechanism of the valve it is connected to.
In certain applications, such as hazardous environments, guidelines such as NEMA VII aim to improve safety by requiring certain precautions for different types of actuators. Safety should always be a consideration when selecting a valve actuator, and when possible, the safest and most reliable option based on the application specifications should be used. An actuator should be able to maintain the fail-safe position should a fire break out, for example. Minimum and maximum supply pressure are among the most important sizing factors to consider. Normal pressure, a metric often provided, should never be used to size an actuator. An actuator must be able to develop enough torque to operate the valve at the minimum supply pressure, ensuring that it functions properly even when supply pressure is at its lowest point.
They are an affordable option for many systems that are easy to install and maintain. Unlike the alternative ball valve, a solenoid valve can be rebuilt by replacing the coils or other internal parts that may have worn out. Manufacturers use solenoids to control fluids, air and gases because the valves can distribute, release, or mix elements with pinpoint control. Since solenoid valves work with a variety of substances, businesses use them in several capacities.
Operators and plant managers are experiencing rapid change as the evolving energy landscape impacts their power plants’ operating profiles. Schneider Electric’s Butterfly Valves and Valve Actuators are a comprehensive offer that meets the application needs of commercial HVAC equipment for performance, efficiency and comfort. As assemblies, the SmartX Valve Actuators and VBB/VBS Series Ball Valves gives users the freedom and flexibility to easily optimize and precisely control a wide variety of applications. Gain actionable insights on installed equipment health to maximize uptime and boost performance.
Therefore, if high-temperature condensate can be recycled as boiler make-up water or used for secondary flash steam, it not only saves industrial water but also saves a large amount of fuel. A flow optimizing trim disc provides the same functionality as a v-port ball. In this case, the characterization is on the discs and the ball is still a full or standard port. The insert is placed directly on the downstream side of the ball and like the v-port it will make the flow increase proportionally with the degree of rotation.
Another advantage of solenoid valves is that they can be reset when the power is off while a reset device needs to be installed on the electric valve to achieve such a function. When an electric current is presented to the solenoid, it builds a magnetic field that pulls the metal armature against a spring, opening or closing the valve. Thanks to their electric activation, they are often used in fluid process systems that require computer connection and automated controls. Reduce commissioning time, routine, preventative & emergency maintenance, downtime, power consumption and outside service costs with K-TORK.
This significantly reduces or eliminates hunting for the right actuator setting, resulting in better control and increased comfort. Siemens offers a 5-year warranty on valves, actuators, damper actuators, sensors, thermostats and meters.
