The high-torque P2~6 Series quarter-turn electric actuators have clutchless manual overrides, raised position indicators, and powder coated aluminum enclosures. Actuators can operate with compressed air between 45 psig and 90 psig . 2-way valves are straightforward components that can help you save energy and money. These valves have an inlet and an outlet port, and are found in basic on/off applications as well as variable flow systems that experience changes in temperature, flows, and pressures.
With the Fisher easy-Drive actuator, you can have the confidence that your control valves will perform as expected, regardless of application conditions. Both gate valves and ball valves are on/off valves that are available in various sizes and materials, as well as different temperature and pressure ratings. Use these actuators for high-cycle applications that require a failsafe in the event of compressed air or power loss. High quality rack & pinion style pneumatic actuators can cycle on or off up to 1,000,000 +/- times when used within specifications. Electric actuators have cycles of 250,000 +/- but are application dependent.

EIM quarter turn products are selected by application requirements of voltage, torque, operating time, and valve shaft diameter. Actuators are made for ball, plug, and butterfly valves as well as quarter turn damper and louver drives. These actuated butterfly valves offer a rotary stem movement of 90 degrees or less, in a compact design. Unlike ball valves, butterfly valves do not have any pockets in which fluids may become trapped when the valve is closed. Valmet offers a wide range of high-performing pneumatic, electric and manual actuators designed to maximize cycle life and improve process efficiency. The Neles B series piston type, N1 series scotch yoke and Jamesbury™ Quadra-Powr™ X spring-diaphragm actuators are solutions that provide exceptionally smooth and reliable actuation for 90° rotary valves.
van điều khiển điện refer to the different ways you can easily apply the use of the valves you are working with. For this, you have different options ranging from electric, pneumatic, hydraulic, and mechanical among others. If you have a specific actuator way you’d rather work with, we’ll ensure to provide that.
After more than 135 yrs, Fisher valve technologies are forging the future of flow control solutions. Reliable Fisher control valves help you meet production schedules, maintain product quality, and improve plant efficiency. One of the benefits is the valve’s ability to continue working at a high flow rate, despite a pressure drop. Since they don’t have a diaphragm they have a greaterCv value, or flow compared to the same size solenoid valve.
An electronic actuator designed for hard work and easy maintenance, it offers quarter-turn and multi-turn control in one non-intrusive actuator. The TEC2000 is different from other actuators that are supposed to be non-intrusive, but require the valve to be opened for fuse replacement. With a separate dual-seated terminal chamber housing the actuator’s primary fuses, EIM’s TEC2000 is truly a non-intrusive actuator.
The control capabilities of the MCV range are based on different characteristics, including split characteristics for DHW applications using heat exchangers, as well as linear and logarithmic characteristics. This means that even the most difficult control requirements in district heating can be met, while still providing instantaneous hot water. For DHW systems, the low slope of the split characteristic in this part of the stroke ensures stable control of the valve in the critical area near the closing position.
These types of actuators are compact and often used in smaller valves, and because they have lower power requirements, they can be configured with an emergency power supply for fail-safe operation. They also have a wide range of capabilities, from smaller actuators delivering a few inch pounds of torque to the largest actuators, which can deliver a million inch pounds of torque or more. Most pneumatic and hydraulic actuators use a cylinder coupled with some mechanism that turns the linear motion generated in the cylinder to the quarter-turn motion required for valve operation. Adding an opposing spring allows for positive shut-down in emergencies.
Prominent & Leading Manufacturer from Ahmedabad, we offer electric valve actuator, motorized high butterfly valve, pneumatic ball valve, industrial actuator control valve, 2 way solenoid valve and actuator valves. Pneumatic and hydraulic actuators – multi-turn – When multi-turn output is required for operating a linear-type valve, such as a gate valve or a globe valve, fluid power actuators are a common solution. While electric actuators are often used for these types of valves, pneumatic and hydraulic actuators are viable options for applications in which electricity isn’t readily available. Kele provides valves and valve actuators that deliver comprehensive control solutions for almost any chilled water, hot water, steam, 50% glycol applications. There are many other applications that exist in the HVAC market and Kele can provide information on those as well when it comes to valve selection.
