Product Description
Application Scenarios
- Industries: Widely used in pipeline systems of petroleum, chemical, food, pharmaceutical, paper-making, hydropower, marine, water supply and drainage, metallurgy, energy, and other industries.
- Media: Suitable for conveying fresh water, sewage, seawater, air, steam, food, pharmaceuticals, various oils, weak acids (limited corrosion resistance due to rubber material), weak alkalis, salts, etc., serving as regulation and shut-off equipment.
II. Performance Parameters
(I) Nominal Diameter
- Based on the figure and common product specifications, covers DN50 - DN600 (adapting to different pipeline diameters for various engineering connections). The product in the figure is estimated to be in the common range of DN50 - DN200.
(II) Nominal Pressure
- Typically includes PN10, PN16, etc. (flexibly selectable according to actual system pressure conditions, suitable for medium and low-pressure systems in general industrial and civil buildings, water supply/drainage, and light chemical industries).
(III) Test Pressure
- Shell Test Pressure: 15bar (for PN10), 24bar (for PN16), used to detect valve body strength and ensure pressure-bearing safety, verifying casting and machining quality to prevent cracking or leakage under pressure.
- Seal Test Pressure: 11bar (for PN10), 17.6bar (for PN16), ensuring valve sealing performance by verifying the sealing effect between the seat and disc through pressure testing, reducing media leakage risks.
(IV) Applicable Temperature
- Varies with rubber seat material:
- For EPDM seats: -15°C - +120°C.
- For heat-resistant EPDM: -15°C - +150°C, suitable for different temperature conditions (e.g., hot water, steam tracing systems).
III. Material Configuration
(I) Valve Body
- Materials: Ductile iron (code Q), gray cast iron (code Z), carbon steel (C), CF8 stainless steel (PB5), etc. Ductile/gray cast iron offers high cost-effectiveness and good castability, suitable for non-corrosive or medium-pressure applications; stainless steel for weakly corrosive media (e.g., food, pharmaceutical industries).
(II) Butterfly Disc
- Materials: Electroplated ductile iron (B1), aluminum bronze (B2), 304 stainless steel (B3), 316 stainless steel (B4), etc. The disc in the figure is likely ductile iron with surface treatment (balancing strength and cost), while stainless steel is used for highly corrosive environments.
(III) Valve Stem (Rotating Shaft)
- Material: Stainless steel (e.g., 304, 316), balancing strength and corrosion resistance to prevent rusting and ensure smooth operation over long periods.
(IV) Valve Seat
- Rubber materials: EPDM (X3, suitable for ozone, weak acids/bases, low-pressure steam), neoprene (X4, for air, fresh water, oils), NBR (X5, for water, seawater, oils, excluding oils with extreme pressure additives), etc. The black seat in the figure is presumably EPDM or NBR, suitable for water, air, and weakly corrosive media.
IV. Product Advantages and Features
(I) Design and Manufacturing
- Advanced Design: Utilizes 3D modeling and finite element analysis to optimize structure (e.g., simulating fluid dynamics and stress distribution), ensuring valve body strength, disc rotation flexibility, and sealing reliability.
- Precision Manufacturing: Key components (e.g., valve body sealing surfaces, disc contours) are processed by high-precision CNC machines and machining centers, ensuring dimensional accuracy and interchangeability, compatible with imported pipeline systems and equipment.
(II) Operation and Performance
- Opening/Closing Characteristics: Handle-driven 90° rotation for quick operation with low torque; streamlined disc design reduces fluid resistance and energy consumption (ideal for water supply/drainage and HVAC systems sensitive to pressure loss).
- Sealing and Durability: Elastic rubber seat provides reliable sealing (low leakage in normal conditions); stem sealing design (e.g., packing) prevents leakage; optimized for tens of thousands of operation cycles, suitable for frequent use thousands of operation cycles, suitable for frequent use (e.g., automated control systems).
- Strong Adaptability: Materials and connection dimensions can be customized (e.g., stainless steel for corrosive environments); even the basic soft-seal model can be adapted (e.g., seat material change) to meet different media and temperature requirements.
VI. Installation and Maintenance Guidelines
(I) Installation
- Wafer-Type Installation:
- Place the valve between two pipeline flanges, aligning the valve's positioning holes with the flange bolt holes.
- Insert stud bolts, install nuts on both ends and initially tighten to ensure proper alignment.
- Use wrenches to uniformly tighten nuts on both sides (symmetrical and step-by-step) to prevent valve body deformation and ensure sealing.
- Can be installed in any position (horizontal, vertical, etc.), but allow sufficient space for handle operation.
- Special Note: For use as an end-of-line drain valve (single-flange connection), specify during ordering. Installation adapts to end-flange connections for media drainage.
(II) Maintenance
- Regular Inspections: Periodically check for leaks (between seat and disc, stem area) and handle operation flexibility (no jamming or looseness).
- Maintenance Operations:
- Replace the rubber seat if aged or worn (ensure material compatibility with media and temperature).
- Check stem packing for leaks; tighten or replace packing (e.g., graphite or PTFE) if necessary.
- For long-term inactive valves, manually operate several times before restarting to remove debris and ensure smooth operation.
Relying on CNNC SUFA's technology and manufacturing expertise, this product offers reliable sealing, easy operation, and strong adaptability for general industrial and civil pipeline systems, making it a popular choice for flow regulation and shut-off applications.
