Flanged Ball Valve - Series 02 for Water, Stainless Steel - DN 20; L=120mm BRA.02.622

Product detailed description

This flanged ball valve is commonly used in commercial and industrial applications where reliable shut-off of water or other non-corrosive fluids is required. It is suitable for installation in heating, ventilation and air conditioning (HVAC) systems, potable water distribution networks and chemical processing plants. Installers typically encounter this valve in systems requiring frequent manual operation or automated control via actuators. Its full-flow design ensures minimal pressure drop across the valve seat while maintaining tight sealing characteristics.

The valve is frequently specified for use in medium to high-pressure environments due to its robust construction and compatibility with a wide range of operating temperatures. It is particularly useful in applications where corrosion resistance is essential, such as in coastal areas or facilities handling mildly aggressive media. The split-body design allows for easy inspection and maintenance without complete system dismantling, making it ideal for systems requiring periodic servicing.

These specifications are critical when determining correct valve size and material compatibility for specific system requirements. The stainless steel construction provides long-term resistance to oxidation and scaling, while the PTFE and Viton® seals ensure low friction and stable performance over extended operational periods.Installation and connection To install the flanged ball valve, align the flange faces and secure using bolts conforming to EN 1092-1 standards. Ensure the pipe ends are clean and free of debris to prevent damage to the sealing surfaces during tightening. Verify that the valve is fully open before securing to avoid stress on the body. Confirm that the actuator mounting pad conforms to ISO 5211 specifications if external automation is required. Common installation errors include misalignment of flanges, improper bolting sequence and failure to verify the direction of flow indicated on the valve body.

Compatibility and accessories

The valve is compatible with standard HVAC systems, water supply lines and chemical transfer pipelines. For automated operation, select an actuator that meets ISO 5211 interface requirements. Additional components such as isolation fittings and pressure gauges may be needed depending on the system configuration. Ensure that all ancillary equipment is rated for the same operating conditions and media compatibility.

Technical background for designers

This quarter-turn valve operates via a rotating ball with a central bore which aligns with the pipeline to allow flow or blocks it when turned perpendicular. The stainless steel body resists corrosion while maintaining structural integrity under thermal cycling. The PTFE seat provides low leakage rates and maintains stability across varying temperatures. The Viton® seal on the stem enhances resistance to abrasion and chemical exposure. System designers should consider the valve’s maximum operating temperature and pressure limits when integrating it into larger hydraulic circuits to ensure long-term reliability.

Service and operation

Routine checks should focus on the integrity of the flange gasket and the condition of the actuation mechanism if fitted. Inspect for signs of wear on the ball-seat interface and verify that the locking lever functions correctly. Clean the valve interior periodically if exposed to particulate-laden media to prevent build-up that could impair sealing performance. No scheduled service intervals are specified in the documentation; maintenance should be performed as needed based on observed conditions.

Frequently asked questions

Can this valve be used in steam systems?
No, the valve is explicitly not recommended for steam applications due to limitations in the sealing materials and thermal expansion characteristics.

Is the valve suitable for chemical applications?
Yes, it is suitable for chemical industry use provided the media does not exceed the temperature and chemical resistance limits defined by the materials of construction.

Can the valve be operated manually or with an actuator?
It can be operated manually via the locking lever or integrated with an actuator that conforms to ISO 5211 mounting standards.

What are the key advantages of the split-body design?
The split-body allows for internal inspection and cleaning without removing the entire valve from the system, reducing downtime and maintenance costs.
