SR-512R RF433 Wireless Battery LPG Gas Cylinder Manipulator | Explosion Proof

The SUMRING SR-512R battery-powered wireless gas cylinder manipulator works with matched gas leakage alarms via stable RF433 signal linkage. Once gas leakage is detected, the actuator will automatically close the LPG cylinder valve within 6~10 seconds to isolate gas sources. With ExiIIC T4 Gc explosion-proof certification and full brass valve structure, this gas shutoff device fits residential kitchens, chain restaurants, hotels and commercial gas safety engineering projects. Note: Gas detection alarm is sold separately.

Key Benefits of SR-512R Wireless Gas Cylinder Manipulator

1. RF433 Stable Wireless Linkage 30~40m long transmission range in open space, reliable signal connection between gas detector and valve manipulator without complex wiring construction.
2. Battery Powered Easy Installation DC 4.5V battery supply, no hardwired power layout required, suitable for old kitchen renovation and cylinder gas sites without reserved power sockets.
3. Explosion-Proof Safety Grade ExiIIC T4 Gc Strictly manufactured following GB/T 3836.1-2021 & GB/T 3836.4-2021 explosion-proof standards, safe for flammable LPG gas application environments.
4. Solid Brass Valve Body Corrosion-resistant brass main valve + flame-retardant ABS outer housing, long service life for heavy-use commercial scenarios like restaurants.
5. Fast Emergency Gas Cutoff Receives alarm signal and finishes valve shutoff within 6-10 seconds, minimizing fire and gas poisoning risks after leakage occurs.

How Does the Wireless LPG Gas Manipulator Work

1. The matched gas alarm sensor continuously monitors ambient LPG concentration;
2. When gas leakage exceeds the alarm threshold, the detector sends out RF433 wireless warning signals;
3. SR-512R manipulator receives the signal and drives the valve to rotate and shut off the LPG cylinder automatically in 6-10s;
4. Manual reset is available after on-site gas hazard is eliminated.

Installation Tip: Install this manipulator on the hand valve of gas cylinder, before the pressure reducing valve; mount the gas leakage alarm at proper monitoring position indoors.
