Guidance 1 Stepping Motor

TOKO VALEX ELECTRIC CONTROL VALVE

A stepping motor rotates by a constant angle per pulse.
A stepping motor, also called a pulse motor, is a motor that rotates in synchronization with a command pulse signal. The
principle of rotation of a simplified 2-phase, 8-pole stepping motor model is shown in the figure below.
A stepping motor consists of a stator with windings and arotor using a powerful neodymium magnet. Energizing theNSstator windings to generate a magnetic force is called
StatorStatorexcitation. By sequentially exciting the multiple stator
SNwindings based on the command pulse, the motor rotatesSS
stepwise, utilizing the action of attraction and repulsion
RotorRotor
between the magnetic poles of the stator and rotor. The(Permanent magnet)(Permanent magnet)
rotation angle of a stepping motor is always determined by
the constant mechanical accuracy (motor structure andmachining accuracy) for each command pulse signal.
Therefore, a stepping motor performs highly accurate
positioning control.

Guidance 2 Open Network
An open network is an industrial network, the specifications of which are made public and can be commonly used by manyusers and manufacturers.
Open networks are roughly divided into the following two types.
1. Those specified by organizations and associations in consultation and recognized as official standards.
2. Those developed by specific manufacturers and organizations and established as de facto standards as a result of promotion activities.
Both types have well-organized and integrated specifications and are available to everyone for many purposes. Either one canconnect different manufacturers’ devices (multivendor devices) and brings many benefits to users.
Currently, many types of open networks are expanding their tempo of popularization according to the applicable field andcountry in the market.

Two-way control valve for acid andalkali service (Resin made)Globe type single seated control valve forwater, steam, and gas service

Three-way control valve for mixing
and dividing

The T-8210 type control valve has excellent corrosion resistance toacid and alkali fluid because the wetted part is made of resin. Thevalves provides high seal performance with a gland packinglessstructure equipped with a PTFE bellows.

The T-8110 type control valve is a control valve with a wide rangeof application, from water and steam to gas,etc.

There are two kinds of three-way control valves. One is a mixing
three-way valve which mixes two kinds of fluid into one. The otheris a flow dividing three-way valve which divides fluid into twodirections.

•Cage-type control valve for high-pressure,high-differential pressure,and low-noise service (Double seated cage trim)
A cage-type control valve is a pressure balance control valve which
is applicable to controlling high pressure or high differential
pressure fluid by balancing the pressure in the cage. Trims can becombined according to uses. Applicable to a wide range oftemperature from -196°C to 500°C.

A cooling-type bonnet can be selected.

Angle-type cryogenic controlvalve (Vacuum container mounting)

The T-8910 sanitary control valve is a regulating valve for thesanitary process of products, such as food, drinks, and chemicals.
It minimizes internal residual liquid, features a clamp-type split
structure, and allows ease of disassembly cleaning, thus excellingin terms of sanitary and maintainability.

The T-8800 type control valve controls cryogenic fluid, such as liquid helium whose
service temperature is close to the absolute zero degree. The valve is installed bywelding in a vacuum container. The valve trim has a structure which prevents
galling thermal oscillation at low-temperature operation and provides good shutoff
performance even if the pipe is deformed to some degree due to thermal change.

The T-8020 type control valve is a control valve suitable for verysmall flow control.
The valve is screwed connection type, small and lightweight.

The T-8115 type control valve has a structure equipped with an
external pressure type bellows. The seal perfomance is superior tothat of a general gland structure. Therefore, the control valve isapplicable to controlling toxic fluid and vacuum service.
