MM2XP 2-pole 24VDC Digital Power Intermediate Relay
MM2XP Intermediate relays are usually used to transmit signals and control multiple circuits at the same time. They can also be used to directly control small capacity motors or other electrical actuators. The structure and working principle of intermediate relay are basically the same as that of AC contactor. The main difference between intermediate relay and AC contactor is that there are more contacts and small contact capacity. When selecting the intermediate relay, the voltage level and the number of contacts are mainly considered.
In fact, the intermediate relay is also a voltage relay. The difference from the ordinary voltage relay is that the intermediate relay has many contacts, and the current allowed to flow through the contacts is large, which can disconnect and connect the circuit with large current. -
GJCF-15 APH Gap Control system Signal Transmitter
GJCF-15 APH Gap Control system Signal Transmitter and the Gap Sensor Probe GJCT-15-E are used together to process the signal measured by the probe, and after a comprehensive judgment, an execution command is issued to start the power circuit, so that the sealed sector plate rises, falls or Emergency lift to the upper limit position. It is suitable for detecting the displacement of the air preheater rotor in motion under high temperature and harsh environment.
GJCF-15 APH Gap Control system Signal Transmitter is used in the seal clearance control system of air preheater. The key problem of the system is the measurement of preheater deformation. The difficulty is that the deformed preheater rotor is moving, and the temperature in the air preheater is close to 400 ℃, and there are a lot of coal ash and corrosive gas in it. In such a harsh environment, it is very difficult to detect the displacement of moving objects. -

OWK Series Oil-Water Alarm
The OWK series oil-water alarm detects the oil leakage in the hydrogen-cooled generator units. It has simple structure and is easy to install. It is composed of sheild, float, permanent magnet and magnetic switch. When liquid enters the shell, the float will move. The upper part of the float rod is equipped with a permanent magnet. When the float rises to a certain distance, the magnetic switch will act to turn on the electrical signal, and send out an alarm. When the liquid inside the shell is discharged, the float falls by its own weight, and the magnetic switch acts as a cut-off signal, and the alarm is released. An observation window made of oil-resistant Plexiglas is installed on the shell of the alarm to facilitate the inspection of the liquid level. -
G761-3033B DEH system electro-hydraulic servo valve
G761-3033B DEH system electro-hydraulic servo valve outputs the modulated flow and pressure after receiving the electrical analog signal. It is not only an electro-hydraulic conversion element, but also a power amplification element. It can convert the weak electrical input signal of low power into the output of high-power hydraulic energy (flow and pressure). In the electro-hydraulic servo system, it connects the electrical part with the hydraulic part to realize the conversion of electro-hydraulic signal and hydraulic amplification. Electro-hydraulic servo valve is the core of electro-hydraulic servo system control. -
SM4-20(15)57-80/40-10-S182 actuator electro-hydraulic servo valve
SM4-20(15)57-80/40-10-S182 actuator electro-hydraulic servo valve can provide system closed loop control with exact positional accuracy, repeatable velocity profles, and predictable force or torque regulation.
Typical applications include plastic injection molding and blow molding systems, test and simulation equipment, die casting machines, hydraulic press brakes, animation and entertainment equipment, oil exploration vehicles, and lumber machinery.
This model of the high performance SM4 series offers a wide range of rated flows from 3,8 to 76 l/min (1.0 to 20 USgpm) at ∆p of 70 bar (1000 psi).
The SM4 is a two-stage, modular design, flow control valve which can be manifold or subplate mounted. The symmetrical, dual coil, quad air gap torque motor is integrally mounted to the frst stage nozzle flapper pilot valve with six screws. The second stage utilizes a four-way sliding spool and sleeve arrangement with a mechanical null adjust. Spool position is fed back to the frst stage by means of a cantilever spring. An integral 35 micron (absolute) flter reduces sensitivity to contamination of the frst stage. -

23D-63B steam turbine turning solenoid valve
Turning solenoid valve 23D-63B is designed for turbine steering control. Turning gear is a driving device that drives the shaft system to rotate before and after the steam turbine generator unit is started and stopped. The turning gear is installed on the rear bearing box cover between the turbine and the generator. When it is necessary to rotate, first pull out the safety pin, push the handle and hand turn the motor coupling until the meshing gear is fully meshed with the rotating gear. When the handle is pushed to the working position, the contact of the travel switch is closed and the steering power supply is connected. After the motor is started at full speed, it drives the turbine rotor to rotate.
