Pertanyaan yang Sering Diajukan
Pertanyaan umum tentang APOLLO dari 3G Electric.
What materials are APOLLO ball valves typically made from?
APOLLO ball valves are commonly manufactured from bronze, brass, or stainless steel. Bronze valves, such as the manual two-way models with FNPT connections, are rated up to 600 psig CWP and are suitable for water and gas applications. Stainless steel options are available for corrosive environments. The choice of material depends on the fluid type, pressure, and temperature requirements of the system.
What is the difference between two-piece and three-piece APOLLO ball valves?
Two-piece APOLLO ball valves have a body made of two parts, making them compact and cost-effective for general shut-off applications. Three-piece valves, like the full-port sweat x sweat model, allow the center section to be removed for maintenance or replacement without disturbing the piping. Three-piece designs are preferred in systems requiring frequent cleaning or repair.
Are APOLLO double check valve backflow preventers suitable for potable water systems?
Yes, APOLLO double check valve backflow preventers, such as the Series 4A assemblies, are designed for potable water and irrigation systems. They feature bronze construction and ball valve shut-offs, with FNPT connections. These assemblies prevent backflow of non-potable water into the supply, meeting standard backflow prevention requirements for commercial and residential applications.
What handle options are available for APOLLO ball valves?
APOLLO ball valves come with several handle types: lever handles for standard manual operation, locking lever handles for tamper-resistant shut-off, and spring-return lever handles that automatically return the valve to a default position (usually closed) when released. The spring-return option is used in safety-critical systems where fail-safe operation is required.
Can APOLLO ball valves be used with press-fit connections?
Yes, APOLLO offers ball valves with press x press connections, such as the 1/2 in bronze model rated at 300 psig CWP. Press-fit connections allow for faster installation without threading or soldering, using a pressing tool to create a permanent joint. These valves are suitable for copper tubing systems in commercial and industrial piping.
What repair kits are available for APOLLO backflow preventers?
APOLLO supplies complete check repair kits for backflow preventers, such as the kit compatible with the 4ALF205A2F model. These kits include replacement check assemblies and seals for maintaining the backflow preventer's performance. They are sized for specific valve sizes, like 1 in, and are used to restore functionality without replacing the entire assembly.
