GY-681-4 Plastic Pneumatic combination switch

Product Overview

This 6-compartment pneumatic combination switch, developed by the DESEINOR brand, is an aluminum pneumatic control switch valve designed as a total-of-six-control unit specifically for oil tank trucks. It serves as a core component of the oil tank truck's pneumatic control system, used to centrally control pneumatic components such as emergency shut-off valves, under-tank valves, and vapor recovery valves of multi-compartment oil tank trucks. It enables independent compartment control and emergency shut-off functions, and is widely applied in safety management scenarios of finished oil transportation tank trucks.

Main Control Module: Equipped with a red 'Master switch' main switch, which acts as the total air source control end. Pressing it can quickly cut off all compartment air circuits to achieve the emergency shut-off function.

1、 Compartment Control Module: 6 sets of independent black control buttons (numbered 1-6) that can individually control the pneumatic valve operations of 6 tank compartments, supporting single-compartment or multi-compartment simultaneous operation.

2、 Pneumatic Interface: Uses standard quick-connect pneumatic tube interfaces, compatible with 6mm specification pneumatic tubes, offering convenient installation and reliable sealing.
