In a hydraulic control system for remotely controlling
a valve, it is essential that the position of the valve
be exactly detected for satisfactory operation of the
entire system. Specically designed and built for this
purpose is the OVAL Valve Position Indicator
(owmeter), which, connected in the actuator line of
the valve (a buttery valve, for example), enables the
operator to learn the operating status of the valve at
a glance by detecting the quantity of hydraulic oil
which has been transferred from time to time.
Contain ing an integral potentiometer and
microswitches, this lightweight and compactly built
OVAL Valve Position Indicator (flowmeter) offers
electrical signal transmission to a remotely located
point.
(1) Remote readout capability makes this indicator best suited for a centralized supervisory system.
(2) Easy to maintain with simple, sturdy and compact design.
(3) Positive displacement type owmeter (OVAL gears) oers outstanding metering accuracy and reliability.
(4) Owing to integral microswitches and potentiometer, the system designer can build a wide choice of
control systems with ease.
(5) The pointer comes into contact with the stopper at 97 to 100% of valve actuator capacity and the
remaining 0 to 3% capacity is absorbed by the slip friction clutch. Therefore, the pointer position is
automatically corrected each time the valve is opened or shut.
