HEP 15/16/17 Electro-pneumatic Positioner

HEP 15/16/17 EP positioner adopts dynamic balance principle and converts electric signal of the regulator into pneumatic signal of control valve, so as to ensure rapid and proper locating according to the signal output from the regulator, meanwhile the flow characteristic or action type of control valve can be changed .

KZ03 Air-filter Regulator

Kz03 air-filter regulator is used to filtrate the impurity. water and oil dirt in compressed air and stabilize the pressure to be required. It can supply required air supply and is necessary for various pneumatic instruments.

Standard Specification

VF01 Booster

VF01 booster is a high capacity air relay that can increase working speed of the actuator and decrease time lags. It can markedly advance the response rate of actuator when the transmission distance of output signal from pneumatic adjustor is so far or the capacity of actuator is larger. There is no regulating screw on VFo1 , therefore it can overcome overshoot or vibration.

Standard Specification

VF02 Air Lock

VF02 Air lock is an auxiliary element of pneumatic combination instrument. It can automatically cut off the path of the regulating instrument and control valve to ensure that the opening of the control valve is stopped to failure position, so as to keep normal operating; while the air failure eliminated, the work automatically gets right, and therefore VF02 air lock is the safe protector of automatic control loop.

VF04D Explosion-proof Limit Switch

VF04D Explosion-proof limit switch is one kind of field instruments checking valve state, which is used to output valve open or close position as open/close contacts signal. These signals are accepted by program - control system or sampled by computer , then confirmed and conducted the next program. This product can be used in the important valve interlocking and remote alarm.

Standard Specification

VF04E Limit Switch

The VF04E limit switch is a field instrument for detecting the valve state in the automatic control system. It is used to output the open or closed position of the valve as a DI/DO (contact) signal which will then be received by the prograr controller or searched and sampled by the computer to initiate the next prograr after confirmation. It can also be used as an important valve interlock protectior andremotealarmindicator inthe automatic controlsystem.

VF04D-L Linear Limit-switch

VF04DL linear limit switch is one kind of EP switch that is used to restrict the limit motion position of mechanical device. It takes advantage of collision of mechanical motion component makes (trigger mechanism ) to make the contacts realizing switch on or switch off circuit. It can convert the mechanical shift to electrical signal, thus controlling mechanical action or process controlling. In general, this kind of limit switch will be used to restrict position or stoke, so that the moving machine can be moved via certain position or stroke , such as auto-stopping , reverse motion . variable motion or auto-reciprocating motion etc.
