Product Overview
The HN63 Flanged Gate Valve is an EN/DIN wedge gate valve for general industrial pipeline isolation service. It is designed for fully open or fully closed operation and is not intended as a primary throttling valve.
Typical applications include industrial water, drinking water, steam, air, selected non-aggressive chemical media, petrochemical and refinery utility lines, coke-oven gas, mining service and metallurgical industry pipelines.
HN63 covers DN40 to DN1000 with PN6-PN16 service range according to the source catalog. Final selection should be confirmed according to pressure rating, medium, operating temperature, installation position and project documentation requirements.
Key Features
- Wedge gate design: Suitable for pipeline isolation where low resistance in fully open position is required.
- Rising non-rotating stem: Source catalog describes rising, non-rotating stem construction.
- Slow opening operation: Gradual stroke movement helps reduce hydraulic and thermal shock risk.
- Large size coverage: DN40-DN1000 range for water, steam, air and general industrial pipeline systems.
- Manual or actuator-ready options: Handwheel, gearbox, electric actuator and ISO 5210 actuator-ready configurations can be discussed.

Frequently Asked Questions
Q: Is HN63 suitable for throttling service?
No. HN63 is a gate valve intended for isolation service and should normally be operated fully open or fully closed.
Q: How is HN63 different from HN64?
HN63 covers DN40-DN1000 and PN6-PN16 service range, while HN64 is a higher-pressure gate valve series covering PN16-PN100.
Q: Can actuator-ready versions be supplied?
Manual handwheel operation is standard. Gearbox, electric actuator and ISO 5210 actuator-ready configurations may be discussed based on project requirements.
