PU Seated Knife Gate Valve
MVI PU sealed knife gate valve has a great abrasion resistant performance,is a new design specialized for mining industries.

In general mining process, high abrasion is one of the biggest problems for pipeline equipment, such as fittings, pumps, and valves. So request the equipment not only with great sealing performance but also need has a great abrasion resistant performance which was expectant. MVI MQPZ series PU seated knife gate valve is a new design specialized for mining industries, for example, Taconite, Iron Ore, Copper Ore, Gold Ore, Phosphorus Ore, Lead Ore, Coal Ore, etc.

Product Description:

QP Series No groove bi-directional seal knife gate valve, cast iron body with the over all structures of the knife gate valve, including the body, gate, and U-shaped flexible seal at the bottom of the body with grooves. When the valve is closed, the bottom of the gate edge contact with the seal and then compress the seal into the groove of the body and sealed gate realization.When the gate opens, separate gate from the bottom edge of the sealing, seal will bounce to same level as groove, which will prevent the media sediment accumulated in the body cavity of the groove, no clogging, no residue, pipe easy to clean, so as to effectively improve the sealing effect knife gate valve to prevent leakage when the valve is closed.


Features:

Bi-directional seal

2PC Body design

Full port design

Fluid without retention in valve body

Super wearable special for mining

2PC Strong yoke design

Mixed with a variety of materials packing
