Introduction of check valve
Check valve, also known as one-way valve or check valve, its role is to prevent the backflow of media in the pipeline. Includes swing check valve and lift check valve. Swing check valves have a hinged mechanism and a door-like disc that rests freely on the inclined seat surface.

Special valve selection matters needing attention
Most of the fluid media used in the process industry involve oil and gas streams of different corrosive grades. These flow conditions, including medium flow, are considered to be either clean, dirty, or worn (mud conditions), and the difference lies mainly in the number and type of solid suspended particles that cause valve blockage or corrosion damage.
What are the material of butterfly valve
Gray cast iron is suitable for water, steam, air, gas and oil with nominal pressure PN ≤ 1.0MPa and temperature of -10 ℃ ~ 200 ℃.
Professional filter measuring instrument for photometer
The testing steps of professional filters need to be mastered and applied step by step. Today, we will analyze the specific process for you from nine steps. I believe you will have more confidence in the use of the equipment after reading.
Teach you how to calculate the Y filter resistance loss
Y-type filter is an indispensable device on the transmission medium pipeline. It is usually installed at the inlet end of a pressure reducing valve, a pressure relief valve, a water level valve or other equipment to eliminate impurities in the medium to protect the valve and equipment Normal use. The selection of Y-type filter usually involves the calculation of filter resistance loss, so how is the resistance loss of Y-type filter calculated?
Y-type filter for easy cleaning and maintenance
Y-type filter is suitable for gas medium (gas, artificial gas, liquefied petroleum gas and other non-corrosive gas) purification filtration, widely used in gas pressure regulating (skid) station, distribution station and gate station and other transmission and distribution system, to protect the system in the regulator, flow meter, valve and other equipment work plays an important role,
Valve logo and model, entry must see!
Beginners of the valve always mistake the faucet for the valve. In fact, not also, the faucet belongs to the bathroom series in the strict sense. Valve is divided into gate valve, globe valve, butterfly valve, high pressure valve, low pressure valve, fluorine valve, safety valve, pressure relief valve, anti-corrosion valve, filter, check valve, pressure reducing valve, over-flow valve, ceramic valve, medium pressure valve, high temperature valve, low temperature valve and so on.
