• The advantages of common gate valve structure

    1, the valve opening and closing needs more effort. Is compared with the cut-off valve, because whether it is opened or closed, the direction and the movement of the gate and the media flow direction is perpendicular.

    2, the height is big, open and close time is long. Gate opening and closing stroke is larger, the decline is carried out through the screw.

    3, water hammer phenomenon is not easy to produce. The reason is the closing time is long.

    The Advantages of Common Gate Valve Structure

    4, the media can flow in any direction on both sides, easy to install. Gate valves are symmetrical on both sides of the channel.

    5, the length of the structure is smaller.

    6, sealing surface is easy to wear and tear, affect the service life. When the sanitary valve is opened and closed, the two sealing surfaces of the gate plate and the valve seat are mutually friction and sliding, so as to produce the abrasion under the pressure of the medium, and the sealing performance and the service life can be shortened.

    7, the price is more expensive. Contact sealing surface is more complex processing, especially the gate seat sealing surface and more parts are not easy to process.

    8, the body is simple, the structure of short length, good manufacturing process, wide application.

    9, compact structure, good rigidity, smooth channel, small flow resistance, sealing surface of stainless steel and carbide, long service life, the use of PTFE packing.

  • Stainless steel sanitary diaphragm valve

    Manual or pneumatic operation, especially applied for the hygienic and aseptic processes in the pharmaceutical industry. The valve is ideal for fluid control and on / off tasks. Diaphragm provides body seal and valve seat seal. There is no path to the external environment, so the diaphragm is suitable for aseptic processes. 

    When the valve is closed, the pressure pad supported the diaphragm moves toward the sealing surface of the valve body. When the pressure plate moves, the diaphragm bends and is forced into the valve seat area in the center of the valve body, thereby closing the fluid path to the valve body. The sanitary diaphragm valves can be operated manually or pneumatically, and can be controlled by a controller and an electromagnetic valve.

    Stainless Steel Sanitary Diaphragm Valve And Check Valve

    Welded sanitary check valves are used in stainless steel piping systems to prevent fluid backflow.

    Technical data of welding sanitary check valve:

    If the check valve is installed in a vertical pipe, open the valve required pressure is about 300-600kpa, the maximum conveying pressure of 800kpa, temperature ranged according to the seal material selection.

    Welded sanitary check valve material:304 stainless steel

    Sealing ring: silicone rubber (VMQ), fluorine rubber (FPM) three ethylene propylene (EPDM)

    Welding type sanitary check valve is installed in a vertical pipe, open the valve required pressure is about 300-600kpa, the maximum conveying pressure is 800kpa, temperature range according to the seal material selection.

  • Butterfly valve

    General properties

     - Butterfly valve, of which only the Seat and Disc come in contact with the medium

     - Installation possible in both flow directions 

    - Simple installation and maintenance, no additional flange packings requiredfor installation between the pipe flanges 

    - The body of the sanitary butterfly valve is protected by epoxy against corrosion 

    - Tight shut off up to 19.8 barg 

    - Suitable for direct mounting of pneumatic or electric actuator

    The Introduction of Butterfly Valve

     

    Specifications 

    - Wafertype or Lugtype with threaded holes 

    - face to face as per standard DIN3202-3K / ISO5752 series 20 

    - Seatring in EPDM or Buna-N - Pressure class PN10/16 - ASA150 - Top Flange as per standard ISO 5211 for actuator mounting 

    - Secured Stem Process conditions 

    Working pressure: max 19.8 barg dependent on temperature

    Temperature: dependent on the seat material

    The Introduction of Butterfly Valve

    Installing the valves in existing pipelines: 

    1. In order to make mounting easier open the flanges completely. 

    2. Disc must be in a 95% closed position. 

    3. Centre the valve between the flanges and tighten the bolts. 

    4. Open the valve completely and remove the flange separator. 

    5. Tighten the bolts using the nuts by hand only. 

    6. Bring the valve to full open position.

    7. Tighten the bolts until the flanges touch the valve body. 

    8. Test the valve by opening and closing several times.
