  1. STRUCTURAL CHARACTERISTICS & TECHNICAL REQUIREMENTS
  1. Connection Type: Monoflange wafer construction. The valve body has an integral cast flange at the center (monoflange) with bolt holes; both ends are wafer-type sealing faces without flanges.
  2. Installation Method:
    • Valve is sandwiched between two pipeline flanges, tightened by through-bolts connecting both side flanges.
    • Monoflange function: Can be used as support flange fixed to a bracket, as anchor flange to prevent axial movement, or for connection to auxiliary piping/support structure.
    • Bolts pass through monoflange and pipeline flanges for overall tightening.
  3. Sealing Structure: Concentric soft seal design, disc interference fit with rubber seat achieving zero leakage. Seat adopts fully vulcanized process.
  4. Disc Material Advantage: Stainless steel disc, corrosion resistant, prevents sticking due to rust.
  5. Operation Type: Worm gear operation (standard for D371X model):
    • Worm gear transmission, labor-saving operation
    • Self-locking function, can be positioned at any angle
    • Handwheel clockwise close, counterclockwise open, with position indicator
    • Worm gear box IP65 protection rating
  6. Face-to-Face Dimension: According to GB/T 12221 Series 16 short pattern.
  7. Monoflange Load Capacity: The monoflange can bear certain pipeline weight or serve as anchoring point. Suitable for applications requiring intermediate pipe support or anti-vibration fixing.

  1. OTHER REQUIREMENTS
  1. Coating:
    • Body (ductile iron) exterior: Epoxy anti-rust paint, film thickness ≥150μm, color: blue (or as per user request).
    • Monoflange sealing surface to be protected from painting.
    • Stainless steel disc: No coating, natural metal finish.
  2. Protection & Storage:
    • Valve ends protected with plastic caps.
    • Worm gear box with waterproof packaging.
    • Monoflange can be used as lifting point, ensure balanced lifting.
  3. Nameplate: Fixed on worm gear box or body, indicating: Manufacturer, Model D371X (Monoflange Type), Nominal Diameter, Nominal Pressure, Operating Temperature, Body/Disc/Seat Materials, Manufacturing No. and Date.
  4. Warranty: 12 months after commissioning or 18 months after delivery.
  5. Monoflange Load Capacity: This valve’s monoflange is designed for intermediate support and anchoring. Maximum allowable load depends on pipe size and operating conditions. Please consult manufacturer for specific load ratings.
  1. REMARKS
  • Please select below:
    • □ Seat Material: EPDM (Ethylene Propylene Rubber, temp. -10~+80℃, resistant to hot water, aging resistant)
    • □ Seat Material: NBR (Nitrile Rubber, temp. -10~+120℃, good oil resistance)
  • Monoflange bolt holes: Through holes (standard configuration)
  • Matters not covered in this sheet shall be according to technical agreement signed by both parties and GB/T 12238 standard.
  • If monoflange to be used as main anchoring point, please provide pipeline weight, support spacing, and any vibration/dynamic load parameters for strength verification.

This technical data sheet accurately describes the Monoflange Type Wafer Butterfly Valve:

  •  Integral monoflange at valve body center
  •  Both ends wafer type connection
  •  Model: D371X (Monoflange Type)
  •  Materials: Ductile Iron Body, Stainless Steel Disc, Rubber Seat
  •  Operation: Worm Gear

The monoflange provides intermediate support and anchoring capability, ideal for pipeline systems requiring additional stability or vibration control.
