Dimensions
Non-standard DN sizes, wafer or flange types and special face-to-face lengths based on drawings.
OEM & custom fabrication
Custom Solutions
From operating conditions to confirmed project drawings
Non-standard welded valve projects start with the service conditions, installation interfaces and customer documents available for engineering review.
JNS supports OEM supply and drawing-based fabrication for non-standard dimensions, special connections, materials and actuation interfaces. Every project is confirmed on drawings before production starts.
How a custom project runs
A structured path from the first requirement list to packed valves - each step closes with documents both sides can check against.
-
01
Requirement Review
Collect the medium, pressure, temperature, dimensions, connection, sealing and actuation requirements.
-
02
Configuration Proposal
Evaluate the structure, materials, sealing approach and actuator interface against the stated conditions.
-
03
Drawing Confirmation
Confirm overall dimensions, connection dimensions, materials and key technical requirements.
-
04
Manufacturing and Inspection Requirements
Define manufacturing and inspection requirements based on the confirmed project documents.
-
05
Packaging & Delivery Requirements
Confirm marking, packaging, accompanying documents and transportation requirements.
What can be configured
Connections
Welding ends, flanges or custom interfaces matched to the piping standard of the project.
Materials
Carbon steel, stainless steels and wear-resistant combinations selected against medium and temperature.
Sealing
Elastomer, laminated or metal-to-metal sealing reviewed against temperature, abrasion and leakage class.
Actuation interface
Manual gear, pneumatic or electric actuation with mounting interfaces prepared to your control spec.
Coating & protection
Painting systems and corrosion protection aligned with the installation environment.
Project documentation
Confirmed drawings, material certificates and inspection records defined with the order.
VDF-25CS program
The custom welded valve program
VDF-25CS is the frame for drawing-based custom welded butterfly valves: dimensions, structure, connections, materials, sealing and actuator interfaces are reviewed based on the submitted conditions.
- Built on the VDF-25 series welding structure
- Pneumatic or electric actuation options
- Configuration confirmed on project drawings
- Suitable for OEM supply programs
What to send for a first review
The more complete the documents, the faster the configuration proposal. A sketch or an existing drawing is enough to start.
