Product Information

Full details

This Idmar 1" Inch BSP Lever Inline Water Ball Valve is designed for reliable shutoff in drinking water, heating/cooling, industrial installations, and air-conditioning systems. Its key benefit is durable, perfect shutoff performance even after periods of disuse, thanks to its robust brass construction and Teflon sealing. A minor caveat is that it is not ideal for fine-tuning flow rates in throttling applications.

FAQs

What does BSP mean for the thread size?

BSP stands for British Standard Pipe. It's a common standard for pipe threads used in plumbing and industrial applications. The 1" size refers to the nominal pipe size.

Can this valve be used for gas lines?

This valve is specifically designed for liquid applications like drinking water, heating/cooling, industrial installations, and air-conditioning. It is not rated or recommended for gas service.

What is the maximum pressure the valve can handle?

The maximum working pressure for this valve is 3MPa, which is equivalent to 30 bar.

What materials is the valve made from?

The body, ball, pin, and plug are made of brass, and the ball/pin sealing is made of Teflon.

How do I know if the valve is open or closed?

The lever handle acts as an indicator. When the lever is inline with the pipe, the valve is open. When it is perpendicular to the pipe, the valve is closed.

Can this valve be used for throttling (partially opening/closing)?

While it can be partially opened, this ball valve is primarily designed for full shutoff. It does not offer the fine control necessary for precise throttling applications and may not provide consistent flow regulation.

What is the temperature range for this valve?

The valve can operate within a temperature range of -20°C to 180°C.

Troubleshooting

Valve is leaking when closed

Ensure the lever is fully in the closed position (90 degrees). Check for debris on the ball or seat, and clean if necessary. If the leak persists, the Teflon seals may be worn and the valve may need replacement.

Lever is stiff or difficult to turn

Operate the valve several times to break in the seals. Ensure there is no debris obstructing the valve's internal mechanism. If the valve is used in a system with sediment, occasional flushing might help. If excessively stiff, professional inspection may be required.

Thread connection is leaking

Check that the threads are properly aligned and have not been cross-threaded. Ensure adequate thread sealant (e.g., PTFE tape) was used during installation. Tighten the connection slightly, but avoid overtightening.

Valve does not fully close

Verify the lever is at the 90-degree closed position. Check for obstructions or damage inside the valve that prevents the ball from seating correctly. This may indicate internal wear.

Pros and Cons

Pros

  • Excellent shutoff capability, even after long periods of inactivity.
  • Durable construction with brass body and Teflon seals for longevity.
  • Clear visual indicator of valve status via lever position.
  • Suitable for a wide range of temperatures and pressures.
  • Easy to operate with a quarter-turn mechanism.

Cons

  • Not designed for precise throttling or flow regulation.
  • BSP threads may require specific adapters in non-BSP systems.
  • Brass construction, while durable, can be susceptible to certain corrosive environments over very long term exposure.

Setup, Compatibility & Care Instructions

Setup:

  1. Ensure the valve is turned to the fully closed position (lever perpendicular to the pipe).
  2. Clean the threads of the valve and the mating pipe.
  3. Screw the valve onto the male BSP threaded pipe until hand-tight.
  4. Use appropriate tools to tighten further, ensuring a snug fit without overtightening, which could damage the threads or valve body.
  5. Connect the drain valve if required for your application.

Compatibility:

  • This valve features 1" BSP female threads. It is compatible with 1" BSP male threaded pipes and fittings.
  • Ensure the fluid being conveyed is compatible with brass and Teflon.
  • Verify that the system's maximum working pressure (3MPa/30 bar) and temperature range (-20°C to 180°C) are within the valve's specifications.

Care:

  • Periodically inspect the valve for any signs of wear or damage.
  • Operate the lever occasionally (e.g., quarterly) to prevent the ball from seizing due to inactivity, especially in systems with clean water.
  • Avoid using abrasive cleaners. If cleaning is necessary, use a damp cloth.
