Special small-diameter high-pressure valve for mining MGQ
Special small-diameter and high-pressure MGQ valve for mining, specifically designed for automatic control in coal mines, suitable for fire protection in coal mines, dust reduction, and for combined use with jet pumps and underground vacuum pumps. The special small-diameter and high-pressure MGQ valve for mining is compact, lightweight, and highly automated, can be connected to DCS systems; it is not limited by the direction of the medium flow, nor by high or low pressures, nor by positive or negative pressures; it ensures that dirt in the medium does not affect the valve sealing when closed, guaranteeing that the valve does not leak; it can be operated manually without electricity. The valve is made entirely of stainless steel and has two types of connections: internal thread and flange.
