ATEX float valve available for use under powder flow.

ATEX float valve available for use under powder flow.

Widely adopted in pharmaceutical and chemical plants around the world! The pressure loss of the powder flow passing through the float valve during operation is minimal, and turbulence is slight.

The "ATEX Float Valve" is a valve developed through continuous improvements as a passive shut-off valve that blocks the propagation of deflagration in ducts. During an explosion, the float valve, which is latched in the open position by the wind speed of the explosion, moves axially and is fixed in the closed position, thereby stopping the propagation. This fundamentally improves the turbulence, pressure loss, and malfunction caused by the floating of the float valve, which were issues in the past. 【Features】 ■ No gaskets used ■ Pressure-resistant passive shut-off valve ■ Float valve has opening and closing latches ■ Pressure loss and turbulence of the powder flow passing through the float valve during operation are minimal *For more details, please refer to the catalog or feel free to contact us.

Explosion propagation instant shut-off equipment ATEX instant shut-off valve QSV

Explosion propagation instant shut-off equipment ATEX instant shut-off valve QSV

Driven only by air pressure and solenoid valves without using explosives ignition devices or burst panels! Manual and remote operation and recovery testing are possible!

**Overview** The control panel that receives the explosion detection signal drives the electromagnetic valve to block the propagation of flames through the duct. The ATEX instant shut-off valve QSV only uses the control air from the factory instrumentation to achieve pneumatic control for shutting off. It is installed horizontally or at the bottom at a location approximately 2 to 7 meters away from the explosion source (for DN200). **Features** - There is virtually no pressure loss during operation, making it effective against explosion propagation from both directions in the duct. - It draws in factory instrumentation air and maintains the operating pressure with a pressure storage tank. - There are no replacement parts required during operational recovery. - By adopting an air cushion stop mechanism, practical operational tests can be repeatedly conducted with a push button. - Maintenance allows for easy measurement of actual operation, and the closing time (in milliseconds) can be measured using a position switch. - Air purging can be added during valve storage. (FDA-compliant hygienic) *For more details, please refer to the catalog or feel free to contact us.*

Actuator achieves required thrust/distance/stroke with high-speed activation.

Actuator achieves required thrust/distance/stroke with high-speed activation.

An actuator (pin pusher (thruster) / pin puller) that can achieve the required thrust of the piston and operating distance (stroke) in milliseconds.

The rapid generation of energy from the combustion of gas-generating agents allows for the instantaneous operation of equipment and the separation or release of payloads and devices. How about applying this to safety devices? It is possible to replace electromagnetic actuators, mechanical actuators, and pneumatic actuators, as well as to achieve further performance improvements. It can also be applied as a gas cartridge for gas generators (inflators) and actuators. We can respond according to the application, purpose, and required specifications.

[Reference] "Introduction to RIKEN Sensor Technology"

[Reference] "Introduction to RIKEN Sensor Technology"

Cultivating the seeds of trust with RIKEN's sensor technology! We are currently offering technical materials that include the principles of gas sensors and the products we handle.

Our company has made "creating an environment where people can work with peace of mind" a permanent theme. We independently develop and produce industrial gas detectors and various gas sensors that continuously monitor the safety of operations and the maintenance of equipment in locations where gas is consumed, produced, and stored, such as semiconductor and LCD factories, oil refineries, steelworks, various tankers, oil storage bases, underground gas facilities, and volcanic sites, among others. This booklet summarizes the principles of the gas sensors used in our gas detectors, as well as an overview of other products we handle and other sensors we have dealt with in the past. We invite you to read it. [Contents] ■ Application fields of gas sensors: For "creating an environment where people can work with peace of mind" ■ Introduction ■ Gas sensors ■ Other various measurement methods ■ Appendix *For more details, please refer to the PDF document or feel free to contact us.

[Labor Accident Case] Organic solvent poisoning during cleaning of a paint stripping and washing tank for automotive parts.

[Labor Accident Case] Organic solvent poisoning during cleaning of a paint stripping and washing tank for automotive parts.

An incident of organic solvent poisoning occurred during the cleaning of a paint stripping tank for automotive parts painting jigs.

The victim began working around 3:30 PM on the day of the incident, entering the peeling cleaning tank to remove paint sludge. They entered the bottom of the tank to gather the sediment and discharge it outside the tank, but around 4:10 PM, after discharging the sediment three times, they were affected. At the time of discovery, the victim was found collapsed in a crouched position at the bottom of the washing tank and was unconscious. They were transported to the hospital by ambulance, received treatment, and regained consciousness approximately 2 hours and 10 minutes after the incident. [Suggestions] - Workers should wear personal PID monitors while working. - This allows for monitoring exposure conditions and can assist in chemical risk assessments. *For more details, please refer to the PDF document or feel free to contact us.*

[Labor Accident Case] Organic Solvent Poisoning during Painting Repair Work at a Hydroelectric Power Plant

[Labor Accident Case] Organic Solvent Poisoning during Painting Repair Work at a Hydroelectric Power Plant

We will introduce a case where organic solvent poisoning occurred during the painting and repair work at a hydroelectric power station.

During regular maintenance, the internal painting of the draft was carried out, but due to areas left unpainted and poor painting quality, the workers entered the draft to perform finishing touches. One person who was inside the draft during the painting sat down, and another became unable to move, so they were taken to the hospital. Following examinations, both were diagnosed with poisoning from organic solvents. [Suggestions] - Use gas detectors to confirm the effectiveness of ventilation. - Work while checking safety with portable gas monitors. *For more details, please refer to the PDF document or feel free to contact us.*

Emergency Shut-off Valve 'EM/EMV Series'

Emergency Shut-off Valve 'EM/EMV Series'

No operation by electricity is necessary! Introducing an emergency shut-off valve that operates reliably even during a power outage.

The "EM/EMV Series" is a valve that automatically closes the internal flow path due to the pressure difference generated by the flow velocity occurring between the A and B ports when a sudden flow exceeding the set flow rate from the A port to the B port occurs due to a failure such as a pipe breakage on the B port line. This valve instantaneously cuts off the flow of hydraulic oil from the A port. There are two types available: "EM," which shuts off only the installed piping, and "EMV," which is installed on multiple pipes and shuts off other pipes in conjunction when one of them operates. Additionally, we also offer the "EMS/EML/EMVL Series" with sensors. 【Features】 ■Instantly cuts off the flow of hydraulic oil from the A port ■No electrical operation is required, ensuring reliable operation even during power outages *For more details, please refer to the PDF materials or feel free to contact us.
