Sanitary Threaded Butterfly Valve

As a professional China supplier, DIYE VALVE, this sanitary threaded butterfly valve is ideal for small-scale hygienic pipeline systems with limited space that do not require frequent disassembly and cleaning. As a trusted manufacturer, we deliver stable performance and cost-effective solutions for global hygienic applications.

Product Introduction

1. Hygienic Flow Channel Design

The flow channel of the Sanitary Threaded Butterfly Valve body is mirror-polished (standard Ra≤0.8μm, custom Ra≤0.4μm available for sterile working conditions), featuring no grooves or dead corners. It eliminates medium residue and bacterial growth, fully meeting the requirements for CIP in-line cleaning and complying with hygienic production standards.

2. Customizable Material Selection

For the valve body and disc of the Sanitary Threaded Butterfly Valve, 304 stainless steel (for conventional working conditions) and 316L stainless steel (for severe corrosion-resistant working conditions) are optional. Sealing parts can be selected as follows: EPDM (for conventional media), silicone rubber (for high-temperature sterilization), fluororubber (for strong acid-alkali/oil media).

Optional Drive Modes

● Manual type: Equipped with anti-slip stainless steel handle/handwheel with a limiting device, featuring intuitive operation. Suitable for small-caliber pipelines with low-frequency operation and cost-effective.

● Pneumatic type: Equipped with a hygienic pneumatic actuator with a positioner/position feedback function, enabling remote on-off control and adjustable opening/closing speed. Ideal for automated assembly lines.

● Electric type: Equipped with explosion-proof/general electric actuator, supporting 0°~90° stepless adjustment for precise flow control. Suitable for unattended, high-precision working conditions such as pharmaceutical preparation conveying.

About us

1. Factory-Direct Pricing Advantages

All core components of our Sanitary Threaded Butterfly Valve are self-manufactured with no intermediate trading links. For the same specifications, our 304/316L hygienic butterfly valves are 40%-60% lower in price than imported brands and 15%-25% lower than industry peer traders, significantly reducing customers' procurement costs.

2. Flexible Ordering & Customized Quotations

We support small minimum orders for Sanitary Threaded Butterfly Valves while retaining price advantages, and tiered discounts are available for bulk purchases. We also provide customized configuration quotations, with drive modes and seal materials selectable on demand to avoid unnecessary cost expenditure.

3. Reinforced Packaging for Long-Distance Shipment

Packaging is customized according to the transportation method: for sea freight/international logistics, we use thickened hard cartons fixed with wooden pallets that comply with IPPC fumigation standards for direct customs clearance; for small-batch courier delivery, shockproof foam filling is adopted to prevent extrusion and deformation throughout the entire transportation process.

FAQ

Q: What is the export HS code for Sanitary Threaded Butterfly Valves?

A: Main HS code: 8481804000 (Other butterfly valves, applicable to the vast majority of Sanitary Threaded Butterfly Valve). It can be fine-tuned according to specific specifications (e.g., caliber, actuation method) for export. We can provide the accurate HS code and customs declaration documents corresponding to export customs clearance.

Q: Can non-standard sanitary butterfly valves be customized?

A: Yes, we offer customization for sanitary butterfly valves, supporting the customization of non-standard dimensions and special structures: ① Non-standard calibers/connection methods (e.g., unconventional clamp chucks, special welding bevels); ② Special seal materials (e.g., ultra-low/high temperature resistant seals); ③ Customized actuation accessories (e.g., pneumatic actuators with explosion-proof devices, electric actuators with remote control modules).

Q: What are the specific requirements for sanitary butterfly valves to support CIP/SIP?

A: CIP (Clean-in-Place) compatible: The flow passage is dead-angle free with a smooth polished surface, allowing the cleaning agent to flow through the entire passage without residue and no need for valve disassembly. SIP (Sterilize-in-Place) compatible: Seals have a temperature resistance of ≥121℃ (Silicone/FKM), and the valve body material can withstand high-temperature steam sterilization at 121℃~135℃ with no deformation or material precipitation after sterilization.

Q: How can overseas customers confirm that the welded butterfly valve matches the dimensions of their existing pipeline?

A: DIYE provides detailed bilingual (Chinese-English) dimension parameter tables, clearly indicating key dimensions such as Nominal Diameter (DN), Outer Diameter (OD), welding bevel angle, valve body length, and flange standard. The product complies with international general standards including 3A, ASME, and DIN. Meanwhile, we can customize the valve body dimensions according to the pipeline drawings provided by customers, conduct pre-dimension verification and simulated installation to ensure direct butt welding upon delivery, avoiding dimensional deviation issues.

Q: Welded butterfly valves are fixed connections and cannot be disassembled. How to perform daily maintenance and replace seals?

A: Daily maintenance can be completed through CIP (Clean-in-Place) online cleaning without disassembling the valve body. It is only necessary to regularly check the stem tightness and operational flexibility. If leakage occurs due to aging or damage of the seal, first close the upstream and downstream pipeline valves, empty the medium, disassemble the stem end cover to directly take out the old seal, and replace it with food-grade seals (EPDM/Silicone/FKM) certified by FDA/3A of the same specification. No pipeline cutting is required, which significantly reduces maintenance costs and downtime losses.
