Flange Wafer Type Butterfly Valve Exporter From TJL

Product Description

Functional Role and User Base

This butterfly valve is designed for controlling flow in pipelines handling diverse media such as water, sewage, steam, chemicals, and oils. Its wafer-style flange connection enables easy installation between pipe flanges without complex fittings. Users include municipal facilities, industrial plants, and production lines requiring flow regulation with minimal pressure loss and reliable sealing.

Technical Specifications and Standards

Constructed from materials like ductile iron, stainless steel, and cast steel, this valve meets standards including BS EN593, API609, and DIN3354. It features a valve plate with rubber seats to enhance sealing under vacuum and varying pressures. ISO5211-compliant flange drive mounting and ±100°C temperature range broaden its applicability. Testing complies with EN12266-1 and API 598, supporting quality assurance.

Applicability and Performance Fit

Suitable for applications demanding corrosion resistance and low operating torque, this wafer butterfly valve fits industries such as chemical processing, water treatment, and food production. Its compact design supports installation in confined spaces while maintaining flow efficiency. The valve’s shaft sleeves and integral stem contribute to smooth, leak-minimized operation in both new system builds and maintenance replacements.

Product Advantages

Procurement-Relevant Design

The valve’s wafer-style flange connection simplifies sourcing and installation, reducing need for additional clamping components. Standardized mounting flanges compatible with various actuator drives facilitate integration with automated systems. Materials selection aligned with international norms supports supplier evaluation for applications in corrosive or sanitary environments.

Operational Fit for Business Use

Certified testing and dimension standards provide a reliable baseline for quality control during procurement. Shipment lead times of 15 to 30 days accommodate project scheduling needs. The supplier accommodates sample requests and customization inquiries, which can assist OEMs and distributors in validating product suitability for specific industrial processes.

Flange Wafer Type Butterfly Valve Product Structure Features:

1. Top flange: standardized drive device flange, conforming to ISO5211

2. Body: Ductile iron and other applicable materials are used.

3. Plate: The streamlined valve plate effectively reduces pressure loss and flow loss. The edge of the valve plate is spherically processed and hand polished. It has the characteristics of low operating torque, long valve seat life and good sealing performance. It can be selected according to a variety of media materials.

4. Rubber valve seat: one-piece valve seat, suitable for all for all kinds of working conditions, extremely low torque value, wide rubber surface and flange joint surface at both ends of the valve, no special flange for clamping butterfly valve, rubber seat for installation bonding to the valve body is more suitable for pipelines with higher vacuum degree to avoid the valve seat moving and deforming due to the vacuum negative negative pressure of the pipline.

5. Valve stem: Central type integral valve stem design, two-way sealing without leakage, installation without restriction of flow direction.

6. Shaft sleeve: copper alloy, more wear-resistant and effectively reduce torque.

7. "O" ring: NBR nitrile rubber, effective dust proof and internal leakage.

8. Pin: conical pin, which can effectively transmit torque and effectively seal without leakage.
