  • All-stainless lever components prevent corrosion in harsh environments
  • Blowout-proof stem design contains pressure under extreme loads
  • Adjustable packing gland allows field maintenance without valve removal

Standard Port Ball Valve for Industrial Piping

The Apollo 7650501A is a 1 inch FNPT stainless steel ball valve designed for inline installation in plumbing and fluid control systems. It features a standard port configuration and spring return handle that automatically returns the valve to the closed position when released. All lever components are constructed from stainless steel for corrosion resistance.

Spring Return Handle and Blowout-Proof Stem

The valve operates with approximately three times the torque of a standard valve due to the spring return mechanism, which requires secure mounting and actuator clearance in the piping layout. A blowout-proof stem design and adjustable packing gland enhance sealing reliability under pressure. Carbon and graphite reinforced MPTFE seats provide chemical compatibility across a range of media.

Suits Systems Requiring Fail-Safe Closure

This valve suits installations where automatic return to the closed position is a safety or process requirement, such as drain isolation or emergency shutoff. It meets NACE MR0175 2000 and MR0103 2012 standards for sour gas service. Builders needing a spring return to open function or a full port design should look at other configurations.

Questions about this item

Will the spring-return handle still close the valve after thousands of daily cycles?

The spring-return-to-close mechanism is built into the 76-500 series design; operating torque runs about three times a standard valve, so the handle returns reliably under normal service.

How much heat does the stainless body and graphite-reinforced seats transmit when the valve runs all day?

All lever components are stainless steel and the seats use carbon-graphite reinforced MPTFE, materials chosen for stable performance during continuous operation.

My piping is 1-inch FNPT — does this valve thread straight on without extra fittings?

Yes, the 1-inch FNPT threaded ends match 1-inch FNPT pipe directly; no additional adapters are required for installation.
