The DIN Standard Angle Type Bellows Sealed Globe Valve represents a critical evolution in fluid control technology. Unlike traditional straight-pattern valves, this angle-body design inherently solves space constraints and drainage challenges common in complex piping networks. By redirecting flow at a 90-degree angle, it eliminates the need for an additional elbow fitting, reducing pressure drop and installation costs.
This DIN Standard Angle Type Bellows Sealed Globe Valve combines a space-saving angle pattern with a multi-ply metallic bellows seal. It is the preferred choice for critical isolation duties in thermal oil, superheated steam, and hazardous gas systems.

Metallic Bellows Seal Element
The heart of this valve is a hydraulically-formed, multi-ply metallic bellows. This eliminates the dynamic seal at the stem, completely preventing external leakage. Unlike conventional packing-only valves, the bellows design ensures zero fugitive emissions – critical for eco-sensitive and high-liability plants.
Optimized Disc Geometry
The conical, streamlined disc profile provides a linear flow characteristic and tight shut-off (up to leakage rate Class VI). This design reduces erosion and vibration, significantly extending the service life compared to standard globe valves.
Redundant Sealing System (Bellows + Packing)
We incorporate a dual-seal architecture. The primary seal is the metallic bellows. Should the bellows ever fail (extremely rare), a secondary PTFE or graphite packing provides an immediate backup seal, ensuring uninterrupted plant safety.
Grease Fitting for Lubrication
An integrated grease fitting allows direct, in-service lubrication of the stem, stem nut, and sleeve assembly. This reduces operating torque and prevents galling on high-cycle applications.
Ergonomic Handwheel
Designed with non-slip ridges and optimal diameter, the handwheel reduces operator fatigue and provides smooth, precise modulation. Heavy-duty construction resists impact damage in rugged plant environments.
Q: Do you have MOQ?
A: No, we do not have a minimum order quantity. Even if you need just one piece, we will produce and supply it. As a flexible factory, we have previously provided a single safety valve to support a customer’s urgent maintenance.
Q: Can you provide other standards?
A: Yes. While our core expertise is DIN Standard Angle Type Bellows Sealed Globe Valve, we can manufacture to other standards (ANSI, BS, JIS) upon request. Simply provide the required standard and pressure class to our supplier team.
Q: Can I get a drawing of the inquiry valves?
A: Yes, but please note that drawing preparation requires some time. Allow sufficient lead time in your project schedule. For special, non-common, or wide-range valves (e.g., DN400 or special alloys), we cannot always provide drawings, as no single factory produces every valve type. However, for all standard DIN configurations, full dimensional and P&ID drawings are available.
Q: How long for a quotation?
A: Usually within 24 hours for standard inquiries. For special valves (e.g., high alloy or non-standard pressure classes), please allow up to 48 hours. We prioritize quick response as a professional China manufacturer.
Q: How about packing?
A: Standard export packing uses sealed wooden cases for corrosion protection. For large sizes (typically above DN200), valves are secured on pallets with stretch film and moisture barrier. All packing meets international shipping standards.
