    Adoptive Standards:

    Valve Design: API 609, MSS SP-67

    Face To Face: API 609, MSS SP-67, DIN3202, BS EN558-1

    Pressure Test: API 598

    Flange Drilling: ANSI B16.1 class125, BS4504 PN10/PN16, DIN2501 PN10/PN16

    Top Flange: ISO5211

    Product advantages:

    1. The product side flanges comply with national, German, Russian, American, British and Japanese standards and other domestic and international standards for multiple pressures, easy connection and wide adaptability, which can reduce the type of purchase and stock.

      2. The thickness of valve body meets the requirement of GB 26640, and the thickness and pressure strength are guaranteed.

      3. The valve body is made of qt450-10 material and has 3 grades of spheroidization rate, with stronger mechanical properties, tensile strength of 450Mpa and extension rate of more than 10%. Compared with cast iron body, the tensile strength of the same thickness is twice that of cast iron body, and the applicable working pressure is higher.

      4. The seat is made of imported rubber material with 50% adhesive content.The valve sealing is reliable, the opening and closing moment is stable, the valve seat has a long service life, and the opening and closing times can reach more than 10000.

      5. The seat is a wide-edge seat, which is favorable for valve installation, wide contact surface with flange boss on pipeline, reliable sealing performance, and the installation precision is lower than the narrow-edge seat. Seat axial with concave table, with o-ring, can realize seat axial secondary seal.

      6. The valve shaft and valve body are equipped with 4 oil-free bearings and 3 o-type seals. The valve shaft supports more vigorously and the axial seal is more reliable.

      7. Ultrasonic cleaning shall be carried out before packing of each valve, so as to prevent contamination and particulate impurities from remaining in the valve body, ensure cleanliness of the valve and prevent contamination of the water body of the pipeline by the valve itself.

      8. The body is sprayed with epoxy resin plastic powder from Aksu, a world-famous brand, which can be deposited thicker and have stronger adhesion after melt curing. 

      9. On the packaging: each valve of wesdomis individually packed with PE heat-shrinkable film, with built-in drying agent to isolate air dust and prevent the valve from being polluted by damp.

      10. The position of the sign table is humanized and set on both sides of the valve body. After installation, it is convenient for users to view.The sign is made of 304 material, with laser marking. The writing is clear and lasts for a long time.Fixed with stainless steel rivets, more beautiful appearance and stronger connection.

      11. The bolt is made of 304 material, with stronger anti-rust ability.

      12. The pin with the pin butterfly valve adopts the tempering treatment, with high strength and wear resistance, and the connection is safe and reliable.

      13. Each product of wesdomhas its own QR code mark and unique ID number from accessories to finished products.By scanning the codes, the inspection results of each stage in the production process can be inquired to achieve traceability of product quality.

    Standard Test :

    Body Test: 1.5 times the working pressure with water. This test is performed after valve assembly and with disc in half position open, it is called as a body hydro test.

    Seat Test: 1.1 times the working pressure with water.

    Function / Operation Test: At the time of final inspection, each valve and its actuator (Flow-Control Lever / Gear / Pneumatic Actuator), under goes a complete operating test (Open/Close). This test carried out without pressure and at ambient temperature. It ensures the correct operation of the valve / actuator assembly with accessories such as solenoid valve, limit switches, air filter regulator etc.

    Special Test: On request, any other test can be carried out according to special instruction by client.
