Product Details

Mining explosion-proof electric manual dual-purpose gate valveProduct Introduction

It is a valve suitable for explosive environments such as coal mines and chemical plants, with both electric control and manual operation functions, supporting remote signal control and complying with explosion-proof standards.

Product Features

Explosion proof rating: Compliant with BT4 explosion-proof certification, the shell is made of solid aluminum or 304 stainless steel material, and can withstand internal explosive pressure ≥ 1.5MPa. ‌

Control mode: Supports various control modes such as conventional coal safety explosion-proof switch type, intelligent integrated switch type, intelligent integrated regulation type, etc. It can accept switch signal, 4-20mA DC analog signal, and bus protocol control. ‌

Manual operation: When the power is cut off, the valve can be manually opened/closed, and there is a Φ 12mm operation hole on the top surface, equipped with special tools for emergency operation.

Applicable media: Suitable for media such as water, steam, oil, nitric acid, acetic acid, etc., with a working pressure of up to 16MPa and a working temperature range of -29 ℃ -300 ℃. ‌

　　Mining explosion-proof electric manual dual-purpose gate valveTechnical Specifications

Nominal diameter: DN50-DN300mm (coal mine), DN15-DN1800mm (industrial pipeline)

Nominal pressure: PN0.6-32.0MPa

Power supply voltage: AC660V/380V

Transmission structure: Adopting worm gear reduction mechanism, transmission efficiency>92%. ‌

Application scenarios

Mainly used in scenarios requiring explosion-proof control such as underground automation transformation in coal mines and petrochemicals, such as fluid cutoff or flow regulation.

Combining electric control and manual operation functions, it is suitable for flammable and explosive environments such as coal mines. Its core advantages include:

Explosion proof safety

The shell adopts explosion-proof structure design and selects explosion-proof materials, which can effectively isolate electrical sparks or high temperatures, avoiding the risk of explosion in hazardous environments such as mines.

Dual control mode

Supports both manual operation and electric control modes. In case of power failure, emergency operation can be performed manually to ensure system reliability; The electric mode supports remote or automated control to improve operational efficiency. ‌

sealing reliability

Adopting pressure self tightening sealing or valve body and valve cover gasket structure, the sealing surface between the valve disc and valve seat is treated with hard alloy spray welding, which has strong wear resistance and low risk of medium leakage.
