The Kofloc 6800 backpressure valve is a kind of relief valve that keeps the pressure at the front stage of a valve constant. It can easily and quickly control the pressure of a tank with a large buffer and remove the constant fl ow of a mixed gas, which cannot easily be done by general regulation valves with a subsequent stage controlling function. This new concept of pressure regulation has been attracting much attention.

• Tank pressure control
• Constant flow control of mixed gas

Installation of the Tokico emergency shutoff valve is required at various industrial equipments by the High Pressure Gas Safety Law and the Fire Defense Law.

In the MB series of emergency shutoff valve, CO2 gas cartridge with high initial torque is adopted as drive source, and ball valve making smooth movement is adopted at the valve part.

It shutoffs urgently or opens the pipelines of various fluids and is most suitable as safety disaster prevention equipment which prevents second disaster from occurring.

Aichi Tokei's governors are actively working at various locations for energy-saving, labor-saving on energy control, and providing safe supply of gas.
The ones introduced here are Aichi Tokei's standard governors.

•Governor for high temperature gas
•Governor with the precise adjustment handle
•Governor for gas that contains sulfide
•Other special governors

If gases escape through leaks in piping systems (e.g. untight screwed connections, corrosions and so on) ultrasonic noises are generated. By means of LD 400 even the smallest leakages which cannot be heard by the human ear can be detected even from distances of several meters. LD 400 transforms the inaudible signals into a frequency which can be identified. By means of the comfortable sound-proof headset these noises can be realized even in extremely noisy environments.

Due to a particularly designed acoustic trumpet a better focusing of the acoustic waves is achieved. This acoustic trumpet acts like a directional microphone while interfering ambient noises are cushioned and the accurate localization of the leakages is eased even in areas which are difficult to access.

RCM general purpose Flo-Gard II flow switches (liquid) reed switches make or break contacts by detecting the position of a magnet permanently attached to the bellow. 

Our reed switches can also be ordered for use in hazardous location (Option IS),  when fitted with

LED's (Option LED) it provides viewing at a glance when flow rate goes below or above the set point  and makes field calibration easy.
