The following are the representative application industries of this valve. Since butterfly valves can be applied to almost all industries (as long as the temperature and pressure are in line), many industries have not been listed.
Lug type butterfly valve ensures zero leakage with API 609-certified PTFE/metal seals. Eared flange maintains uniform sealing pressure for petrochemical pipelines.
Lug valve withstands 20bar water hammer with 400% higher bolt shear strength than wafer valves, ideal for turbine bypass systems.
Handle butterfly valve enables ≤3s actuation to reduce water hammer pressure, with 30-year lifespan (3-5x longer than cast iron valves).
Marine butterfly valves eliminate galvanic corrosion via full stainless construction, compatible with Cu-Ni/Duplex marine pipelines.
Lug type valve with zero-dead-angle design prevents wastewater crystallization. All-metal seal eliminates rubber aging pollution.
Sanitary butterfly valves withstand 150°C steam/acid-alkaline cleaners, food-grade EPDM/FKM seals pass 100,000-cycle tests.

"The last supplier's batch nearly brought the whole project to a halt. A single industrial butterfly valve, no bigger than your fist, left over 200 of us idle for three days. Every minute of that time was money. Thankfully, we found you. We installed these and moved straight to the next phase."Read the Case: A 0.4mm Deviation Nearly Derail a Huawei Project? →
Q: Our factory’s pipeline flange standards are mixed, with national standards and some older equipment using German standards. Can your butterfly valves precisely match them? Will there be connection issues? |
A: Rest assured. JRVAL butterfly valves’ flange connections can be precisely customized to requirements. Whether GB, ANSI, DIN, BS, JIS, or AS standards, we guarantee exact matches. Simply provide specific flange standards and pressure ratings - we ensure trouble-free connections. Every connection hole undergoes Go/No-Go gauge inspection to eliminate mismatch possibilities. |
Q: Some installation spaces are extremely cramped. Previously purchased valves were too bulky. What’s the size of your butterfly valves? |
A: JRVAL lug-type butterfly valves are specifically designed for space constraints. Compact yet robust, our award-winning design (1st prize in Industry Practical & Aesthetic Design) solves spatial challenges while maintaining strength and performance. |
| Q: Are your valves metric threaded? Our fasteners are metric. | A: Standard flange holes use metric threads for easy installation with metric bolts. Special threading available upon request. |
| Q: Seal performance guarantees? Previous leaks caused losses. | A: JRVAL combines premium sealing materials (specified pressure/temperature ratings) with precision machining and flange processing to eliminate internal/external leakage. |
| Q: What information is permanently marked? Can utility tunnel-specific asset IDs be added? | A: Standard markings: JRVAL logo, model, DN/PN, material, heat number. Custom laser-engraved asset IDs, pipeline codes, QR codes, etc., are available for lifecycle management compliance. |
