Notes on flat gate valves

Use, maintenance, maintenance and precautions1. valve before leaving the factory have made strength and sealing test, the use of all connections should maintain the initial state.2. this series of valve operating handwheel is marked with open and close rotary direction, and the upper part of rod is equipped with open and close height gauge for regulating indication.3. when the valve and pipeline welding, the valve should be opened, appropriate to protect the neck with moisture, minimize heat conduction, to prevent damage to the sealing packing parts.4. when the valve is closed, the lever shall not be used. When the gate is closed to the top, the handwheel shall be turned 1/2 so that the gate is in a floating state.5. in the use of the valve should be regularly to the valve cap injection grease joint into the quantitative grease.6., the valve in use, such as vulnerable parts and leakage, should be replaced in time.7., the valve in the overhaul process, the cavity should be cleaned, the assembly should be added to the transmission parts of grease.8. valve storage during the shutdown, the gate should be in the closed position, long-term storage should be placed in ventilated dry place, regular inspection and maintenance.

What does "Z45W-10T" mean?What does each letter stand for?

W is the seal material or lining material code, the valve sealing material is the valve body material, the valve sealing surface material code with "W" said, here stands for brass;The 10 is the pressure code, which stands for PN10, which is often called 1.0MPa;

Is the gate valve clockwise or closed?

In general, the valve is clockwise to turn off. Some of the clockwise rotation of the valve on the move is open

Gate valve is gate valve, gate valve specifications, model code is generally what?

Gate valve is not gate valve, gate valve does not have a fixed specific model
