OEM 5k 10k 150LB PN10 PN16 Wafer Butterfly Valve Exporter, Exporters
Product Description
Key Features & Technical Advantages
Each valve should be cleaned by ultra-sonic cleaning machine, in case of contaminant left inside, guarantee the cleaning of the valve, in case of pollution to the pipeline.
The valve body use high adhesive force epoxy resin powder, helps it adhere to the body after melting.
Marker Plate located on body side of the valve, easy to watch after installation. Material of the plate is SS304, with laser marking. We use stainless steel rivet to fix it, makes it cleaning and tighting.
Bolts and nuts use ss304 material, with higher rust protection capability.
Handle of the valve use ductile iron, is anti-corrosion than regular handle. Spring and pin use ss304 material. Handle part use semicircle structure, with good touch feeling.
Butterfly valve pin use modulation type, high strength, wear-resisting and safe connection.
Non-pin stem design adopt anti-blowout structure, the valve stem adopt double jump ring, not only can compensate the error in installation, but also can stop the stem being blow off.
Each product of ZFA has material report for the main parts of the valve.
ZFA Valve body use solid valve body, so the weight is higher than regular type.

Frequently Asked Questions
Q: What is the advantage of using ultrasonic cleaning for valve production?
Each valve is processed by an ultrasonic cleaning machine to eliminate all internal contaminants, ensuring complete internal cleanliness and preventing potential media contamination in your pipeline.
Q: How does the anti-blowout stem design ensure operational safety?
The non-pin stem features an anti-blowout structure equipped with double jump rings. This design compensates for minor installation tolerances while effectively preventing the valve stem from being blown out under line pressure.
Q: What standards and flange connections are supported?
Our valves comply with face-to-face standards like API609, BS5155, DIN3202, and ISO5752. They support connection standards including PN6, PN10, PN16, PN25, Class 150, JIS 5K/10K/16K, and GOST33259, with an ISO 5211 top flange for actuator mounting.
Q: Can material test reports be provided for key components?
Yes, each ZFA valve product is supplied with comprehensive material reports covering all main components (body, disc, stem, and seat) to guarantee total material traceability and quality compliance.
Q: Which actuator options can be adapted to these butterfly valves?
The valves can be easily configured with multiple actuation options based on project requirements, including manual hand levers, gearboxes, pneumatic actuators, and electric actuators.
