Description
Product Overview
The Manual Right Angle Valve from BROWNIAN is engineered for high‑performance fluid control in demanding industrial and scientific environments. Constructed from 304 stainless steel, the valve body and edge‑welded bellows provide exceptional corrosion resistance and long‑term durability, while the KF16 flange connections ensure a secure, leak‑free seal compatible with ISO‑KF standards.
Designed with a compact 90‑degree geometry, this valve saves valuable space in tight piping layouts without compromising flow capacity. The integrated bellow seal isolates the valve seat from the process stream, allowing the edge‑welded bellows to retract fully when the valve is open, which maximizes conductance and minimizes pressure drop. The seat utilizes an FKM O‑ring that offers excellent chemical compatibility and can withstand elevated temperatures, making the valve suitable for a wide range of gases and vacuums.
Key specifications include a KF16 (NW16) flange on both inlet and outlet, a total weight of 2.2 lb, and package dimensions of 8 × 4 × 2.75 in. The valve is supplied as a complete kit containing two KF16 aluminum wing‑nut clamps, stainless‑steel centering rings, and FKM O‑rings, providing everything needed for a quick and reliable installation.

Usage
This valve excels in applications that require precise flow regulation and high vacuum integrity, such as semiconductor manufacturing, analytical instrumentation, and research laboratory setups. Its robust stainless‑steel construction makes it ideal for handling corrosive gases, while the bellow‑sealed design ensures minimal leakage in vacuum systems down to 10⁻⁶ mbar.
In addition to laboratory use, the valve is well‑suited for industrial processes including chemical processing, pharmaceutical production, and cleanroom environments where contamination control is critical. The KF16 flange interface allows seamless integration with standard tubing and manifold assemblies, reducing the need for custom adapters and simplifying system design.
Maintenance is straightforward: the bellow seal can be inspected visually for wear, and the FKM O‑ring can be replaced without disassembling the entire valve. This serviceability extends the product’s lifecycle and reduces total cost of ownership for end users.

FAQ
What size connections does this valve use?
The valve features ISO‑KF KF16 (NW16) flange connections on both the inlet and outlet, which are standard in many laboratory and industrial vacuum systems. These flanges allow quick and secure attachment using wing‑nut clamps without the need for additional adapters.
Can the valve handle corrosive gases?
Yes. The body and bellows are made from 304 stainless steel, which provides excellent resistance to a wide range of corrosive chemicals. Additionally, the FKM O‑ring seat is chemically inert, further protecting the valve seat from aggressive media.
Is the valve suitable for high‑vacuum applications?
Absolutely. The edge‑welded bellows retract completely when the valve is open, eliminating flow obstruction and enabling conductance suitable for high‑vacuum environments. The sealed design can maintain vacuums down to 10⁻⁶ mbar when properly installed.
How do I replace the O‑ring if it wears out?
Replacement is simple: first depressurize the system and remove the wing‑nut clamps. The O‑ring sits in a machined groove on the valve seat; pull the old ring out, clean the groove, and install a new FKM O‑ring of the same specification. Re‑assemble the clamps, and the valve is ready for use.
What warranty does BROWNIAN provide?
BROWNIAN offers a limited one‑year warranty covering any manufacturing defects. Should a defect arise, contact our technical support team for troubleshooting, and we will arrange repair or replacement in accordance with the warranty terms.
