2 Quarter turn actuators Introduction Econosto offers a comprehensive range of actuators for the product groups butterfly valves and ball valves. Because of the quarter-turn design and the ISO5211 standardised mounting flanges, butterfly and ball valves are well suited to the simple fitting of a pneumatic, electric or hydraulic actuator. In our workshop, our technicians will fit and adjust these actuators onto the butterfly and ball valves ordered by customers, using a mounting kit if required. In addition, the standard actuators can be modified or fitted with accessories as ordered by the customer. Pneumatic actuators Pneumatic actuators are available in 2 versions: double acting and spring return. This actuator type is used when a high switching frequency or fail safe action is required. The design with a minimum number of moving parts makes these actuators extremely reliable. are available for various supply voltages. This actuator type is suitable for applications on sites where there is no compressed air or hydraulic network. Because of the integrated standard features such as limit switches and an emergency handwheel, these actuators are completely functional and compact. Hydraulic actuators Hydraulic actuators convert hydraulic energy into a 90 output rotation, suitable for the actuation of all quarter-turn valves. Due to the high operating pressure, this type of actuator offers a high output torque in combination with a compact body. These characteristics make these actuators suitable for larger valves, and suitable for use in narrow spaces. The strong construction of these actuators ensures a high level of reliability.

3 Pneumatic actuators Type Pneumatic actuators are available in 2 versions: double acting and spring return. The spring return versions can be supplied as spring-to-close or spring-to-open. Apart from the position indicator, all versions are without any external moving parts. This makes these actuators safe in operation, easy to install and virtually maintenance-free. With the compact rack and pinion design and the use of aluminium parts, these actuators are lightweight and compact.

7 Type The Econ compact electric actuators can be used for almost any supply voltage. This multi-voltage actuator has an auto voltage sensing within the specified voltage range. The L-series operates from 15 to 48 Volt AC or 12 to 48 Volt DC. The H-series operates from 80 to 240 Volt AC or DC. External DIN plugs eliminates the need of removing the actuator's cover, when connecting the powersupply. The actuator is also protected against an incorrectly wired powersupply. The protection class is IP65. An electronic torque limiter prevents the actuator from overloading. An internal 4W heater eliminates possible condensation inside the actuator. For remote open/close indication, two potential free contacts are provided as standard. Wiring of these contacts can be done easily by means of the supplied DIN connector. The open/close indicator clearly shows the position of the valve locally. In case of emergency the actuator can be operated by means of a handwheel. The multi functional mounting flange to ISO 5211 has two or three ISO connections with a square interface under 45 and 90 degrees position. This enables mounting of these actuators on almost any quarter-turn valve, such as ball valves and butterfly valves. Specifications Torque: 25 to 350 Nm max.

9 Type EL-series electric actuators are available for several supply voltages. The electric actuators are built to comply with protection class IP65 as a minimum, and optionally can be built to IP67 or explosion-proof classification. The standard thermal switches in the motor windings protect the motor from overheating. Starting from type EL100, the actuators also feature torque to protect the transmission and driven valve from mechanical obstructions. All actuators have standard a high ratio self-braking worm wheel drive, and include a handwheel for emergency manual operation. The handwheel is idle when operating electrically, but can be engaged when emergencies occur. This creates a mechanical connection between the handwheel and the valve. By using the standardised ISO 5211 mounting flange, these actuators can be easily mounted on most quarter-turn valves, such as ball valves and butterfly valves.

11 Type ELQ-series electric actuators can be connected standard to 4 different voltages: 115VAC, 230VAC, 400VAC and 24VDC. The electric actuators are built to comply with protection class IP67 as a minimum, and optionally can be built to explosion-proof classification. The standard thermal switches in the motor windings protect the motor from overheating. The actuators also have an electronic torque protection to protect the transmission and driven valve from mechanical damage caused by obstructions in the system. The ELQ is built standard with a high ratio worm gear transmission with a very high mechanical efficiency. This keeps the noise level very low, there is hardly any free play. It was therefore possible to design an extremely compact and light actuator. The handwheel for emergency manual operation can also be used for setting purposes. A unique feature is that the handwheel is always operable, but does not rotate when the motor is engaged. The ELQ actuator is modular in construction, and can be easily expanded with plug-in modules to a regulating drive, communicating with bus systems. By using the standardised ISO 5211 mounting flange, these actuators can be easily mounted on most quarter-turn valves.

13 Hydraulic actuators Type BRC hydraulic actuators convert hydraulic energy into a 90 output rotation, suitable for the actuation of all quarter-turn valves. The output torque is proportional to the supplied operating pressure and constant over the entire rotation. By means of high hydraulic pressure (normally 135 bar) this actuator gives a high output torque and is therefore a very compact solution for operating larger valves. The rigid design of hydraulic actuators guarantees a long and reliable service life. The BRC actuator is suitable for installation indoor as well as and outdoors, and also as a special option can be ordered for use under water. Robust nodular cast iron housing, compact design, to be extended with different modules such as electric open - close indication, continuous position indication or hydraulic hand pumps for emergency manual operation.
