Product Overview
Introducing the D71X Stainless Steel Wafer Butterfly Valve, a marvel of precise engineering featuring a centric design and wafer-type connections. This advanced valve is crafted for swift opening and closing, offering seamless flow regulation. Its compact framework and reliable sealing make it a preferred choice across water treatment, chemical, food, and pharmaceutical sectors. Ideal for handling corrosive media or high-purity applications, its versatility is unmatched.
Model Breakdown
- D: Denotes Butterfly Valve
- 7: Represents Wafer Connection
- 1: Indicates Centric Design (Valve disc rotates centrally)
- X: Specifies Rubber Seat Material (such as EPDM, NBR, etc.)
Structure & Materials
- Body/Disc/Stem crafted from premium-grade stainless steel (304, 316, or 316L) for exceptional corrosion resistance.
- Seat Ring: Made of durable rubber (standard is EPDM, suitable for temperatures from -20°C to 120°C; alternatives include NBR, Fluorocarbon, tailored for specific media).
- Actuation available in manual (lever or gear-operated) or customizable pneumatic/electric actuators for enhanced flexibility.
Working Principle
The valve disc rotates a full 90° using the stem to modulate fluid flow. The centric design ensures a consistent interface between the disc and seat, providing bidirectional sealing with negligible leakage even at low-pressure differentials.
Key Feature
- Unmatched Corrosion Resistance: Stainless steel combined with rubber sealing, making it perfect for acidic or alkaline environments.
- Minimal Flow Resistance: The full-bore design significantly reduces pressure loss.
- Lightweight & Sturdy: Its compact form, weighing just a third of gate valves, ensures low maintenance requirements.
- Swift Operation: Enables quick control, either manually or automatically, with a 90° rotation.
- Wide Temperature Range: Operates between -20°C to 180°C, depending on seat material.
Applications
- Water Treatment: Ideal for water supply, drainage, firefighting, and wastewater systems.
- Industrial Piping: Suitable for chemical, petroleum, gas, and HVAC applications.
- Food & Pharma: Offers sanitary-grade options with polished surfaces, fully compliant with GMP standards.
Installation & Maintenance
- Installation: Must be done with matching flanges; symmetrically tighten bolts to prevent seat damage.
- Maintenance: Regular inspections for seat wear and stem lubrication are essential; seal replacement is advised every 3-5 years, subject to service conditions.
Precautions
- Avoid exceeding pressure or temperature limits to prevent seal failures.
- Install a filter if the media contains hard particulates to protect valve integrity.
- Note that rubber seats are unsuitable for strong oxidizers like concentrated sulfuric acid; select materials wisely for aggressive media.
Optional Configurations:
- Alternative seat materials available (e.g., PTFE for enhanced high-temperature resistance).
- Extended stem options (ideal for insulated pipelines or specific installations).
- Locking devices can be added to avert unintentional operations.
