APOLLO VALVES 4ALF217A2F Ball Valve, 1-1/2 Inch Size, Bronze

Apollo 4ALF217A2F ball valve is ideal for use in potable water supplies for reducing back pressure. It is ideal for the oil & gas, water treatment and manufacturing industries.

Working Mechanism:

• When the valve is in the open position, the spherical ball's hole aligns with the direction of the pipeline.
• This orientation allows the fluid (liquid or gas) to flow through the valve with minimal obstruction.
• To shut off the flow, the operator is turned 90 degrees, which rotates the ball so that the hole is perpendicular to the pipeline.
• In this position, the flow is completely blocked and no fluid can pass through.

Features:

• Apollo 4ALF217A2F ball valve is tested and approved for low-pressure loss characteristics, ensuring efficient fluid or gas flow through the valve.
• It features a user-friendly design with a modular check valve cartridge that can be easily removed.
• This valve has stainless steel springs that are corrosion resistant and provide robust performance even in harsh operating conditions.
• This ball valve has stainless steel handles and nuts for a strong mechanism that provides reliable shut-off control.
• It has top-mounted test cocks that simplify the testing process, making it easy to verify the valve's functionality and safety.
• This Apollo valve has a modular relief valve for enhanced safety and control.
• It has elastomers that are resistant to chloramine, making it an ideal choice for water treatment and distribution systems.

Frequently Asked Questions:

Q. How do you maintain and service a ball valve?

A. Maintenance involves periodic inspection, lubrication and cleaning of the valve components.

Q. What is the difference between a full-port and a standard-port ball valve?

A. A full-port ball valve has a larger ball and opening, offering minimal flow restriction. In contrast, a standard-port valve has a smaller flow path, resulting in slightly higher pressure drops.

Q. How to prevent a ball valve from freezing or getting stuck in cold weather?

A. In cold environments, insulate or heat-trace the valve and the surrounding pipes to prevent freezing or sticking.

Q. What is the difference between a floating ball and a trunnion ball in ball valves?

A. Floating ball valves have the ball held in place by the valve seats, while trunnion-mounted ball valves have the ball supported by trunnion bearings.
