Linear Electric Actuators
Feature:1. Enclosure precision-machined aluminum alloy castings, dry-powder coating, to provide a rugged, dust-tight, waterproof enclosure designed to meet IP67 and NEMA4X standards.   2. Position indicator all models are equipped with continuous mechanism position indicator. The external stem visual position indicator provides easily read and instantly available stem position. 3. Ambient Temperature Range● Temperature: -30℃ ~ +60℃● Humidity: 30% ~ 95%    4. Over-thrust protection if the output thrust of the drive exceeds of the drive rating, the actuator will shut off by two-step control. The two-step control is as follows: ●First Step: If the output thrust of the drive exceeds the rating, power supply will be turned off by limit switches. ●Second Step: If the limit switches fail, power supply will be turned off by electronic detector. (The function only applies to modulating controller actuator)   5. Adjustable stroke allow users to adjust actuator's stroke to match valve stem's stroke. (Refer to the specifications for stroke range) 6. Manual override provides manual operation without electrical power. When electric motor is operating , manual hand-wheel won't run for safety's sake. 7. Modulating controller ●Output signal: 4-20mA, 1-5V, 2-10V●Input Signal: 4-20mA, 2-10V 8. Action on loss of input signal (Power ON)Stay in place or runs to any preset position.(fully open/ fully close / hold in last place)The function only applies to modulating controller actuator. 9. Action on loss powerOutput shaft stays in last position.

THESE ARE SUITABLE FOR THE ACTUATION OF BALL VALVES, BUTTERFLY VALVES, PLUG VALVES DAMPER ETC , WHICH ARE AVAILABLE TO INTERFACE WITH A WIDE VARIETY OF CONTROL SYSTEMS FOR WATER, TEMPERATURE,
WATER TREATMENT, IRRIGATION, AIR CONDITION, CHEMICAL ENGINEER , FOOD, ETC..
OUR ACTUATORS HAVE BEEN CERTIFIED WITH THE APPROVAL OF ISO9001, ISO14001, CE, OHSAS 18001, RoHS AND CSA INSTITUTIONS.
OUR NON-CLUTCH ELECTRIC ACTUATOR DESIGN WHICH CAN BE OPERATED WITHOUT CLUTCH AND BRAKE ,HAS OBTAINED THE PATENTS IN TAIWAN, CHINA AND USA.
IN ADDITION TO NORMAL FUNCTIONS, OUR SPRING-RETURN ACTUATOR ALSO PROVIDES FAIL-SAFE POSITIONING OF VALVES AND DAMPERS UPON LOSS OF SUPPLY VOLTAGE
THIS DESIGN HAS ALREADY OBTAINED PATENT LICENCING IN TAIWAN, U.S.A. JAPAN AND CHINA.
LINEAR VALVE ACTUATORS PROVIDE THRUST FROM 250 TO 2000KGS AND THE STARTING FREQUENCY IS 1500 STARTS PER HOUR. ALL MODELS ARE EQUIPPED WITH MODULATING CONTROLLERS AND TRAVEL FOR GLOBE VALVE, GATE VALVES AND LINEAR TRAVEL DEVICES. THEY CAN BE APPLIED TO HVAC AND INDUSTRIAL USE, ESPECIALLY FOR STEAM AND HIGH TEMPERATURE EMPLOYMENTS.
WE SUPPLY HIGH QUALITY AND REASONABLY PTICED ACTUATORS.
