Apollo Valves

Non-ASME two-piece valves for utility air and water and tandem drain service; Apollo notes that with trim and body material changes they can be used in severe services with only pressure and temperature limitations, and describes them as considered disposable valves. The 70 Series is a general-purpose bronze valve for vacuum, steam, cooling, and heating; 77C uses a dezincification-resistant bronze body; 77F is a forged brass, full-port valve Apollo positions for HVAC, fuel gas, irrigation, fire protection, and general flow control.

Use it whenThis is the shutoff valve you buy in quantity for utility service and replace rather than rebuild. Do not spec it where somebody will expect to repack or reseat it in the line -- that is what the 3-piece is for.

ASME B16.34 Class 600 and 1500 CWP valves that Apollo states are capable of in-line repair, used in liquid and gaseous fuel service, light duty slurry, low temperature boiler feed water, tandem drain, and hot well drain service. The 83B is a carbon steel Class 600 full port design, and Apollo offers a characterized ball on it with 30, 60, 90 degree and 1/16 inch slot options for accurate flow control.

Use it whenPick 3-piece when the valve has to be rebuilt without cutting it out of the line, or when the service justifies an ASME-rated body. It is the right default for fuel, boiler feed, and light slurry duty, and the characterized-ball 83B is the low-cost way to get throttling out of a ball valve.

ASME B16.34 Class 150, 300 and 600 valves available only with flanged ends. Apollo notes in-line repair is very difficult and better done out-of-line, and that short pattern versions allow use as a gate valve replacement.

Use it whenUse it when the piping is flanged and you cannot thread or weld. The short pattern is the one to remember when you are replacing a failed gate valve and need the face-to-face to match. Accept up front that repair means pulling the valve.

ASME B16.34 Class 150, 300 and 600 top entry valves. Apollo describes a tapered seating design in which the ball and seats are held tight into the wedge by a spring, compensating for wear, cold flow, and pressure and temperature fluctuations that cause parallel-seated floating ball valves to fail. Available in numerous steels and alloys from their South Carolina foundry.

Use it whenThis is the one to reach for when a standard floating ball valve has already failed on you -- mineral slurry, scrubbers, wallboard plants, and other duty where seat wear or cold flow kills the seal. It is also the most configurable product Apollo makes, and the access for rebuilding and clean-out is the practical selling point: the body stays in the line.

ASME B16.34 Class 150, 300 and 600 butterfly valves that Apollo positions as ideal as shutoff valves as well as for throttling applications, with RTFM, fire-safe and metal seat options, in carbon steel and stainless steel bodies, sizes 2 inch to 48 inch.

Use it whenUse it above the size where a ball valve gets expensive and heavy, and when you need to throttle. Metal seat is the option to specify for temperature or abrasion; fire-safe when the service or the spec calls for it.

Pneumatic and electric actuators that Apollo describes as an excellent way to remotely operate quarter turn products like parallel seated ball valves, top entry ball valves and butterfly valves, plus a line of mounting kits to couple the automation to a quarter turn valve of choice.

Use it whenBuy the actuator and valve together when you can -- Apollo mounts and tests the package. The mounting kits matter when you already own the valve, or when you are automating a competitor's quarter-turn body.

Non-ASME metal-to-metal seated valves Apollo lists for tandem sampling, hydraulic isolation, drains, instrument isolation, air supply isolation, and hot well condensate drain, described as considered disposable valves.

Use it whenUse it for fine throttling and instrument isolation on small lines. Metal-to-metal seating is why it handles the sampling and hot-well drain duty a soft-seated ball valve would not.

Line strainers offered across the Apollo catalog.

Use it whenPut one upstream of anything with a seat or a nozzle you cannot afford to foul -- control valves, meters, pumps -- especially on raw water or after new pipework.

Two of the valve categories Apollo lists in their catalog.

Use it whenGlobe when the duty is throttling and the pressure drop is acceptable; gate when it is on-off and you need a straight-through full-bore path. On new industrial work Apollo's own guide points at the short-pattern flanged ball valve as a gate valve replacement, so ask which the site actually wants to stock.

A safety relief valve line listed in the Apollo Valves catalog.

Use it whenThis is code-driven work -- the set pressure, capacity, and applicable code stamp come out of the vessel or system design, so bring the relief calculation to the quote rather than matching a line size.

Pressure reducing valves listed in the Apollo Valves catalog, and also offered within the Apollo Press line.

Use it whenUse it to knock down a high supply pressure to what the building or equipment downstream is rated for. Check whether the job wants a threaded or a press-connect body, since Apollo offers both.

A backflow prevention line listed in the Apollo Valves catalog.

Use it whenSpecified and inspected against local plumbing code for potable water protection. The assembly type is set by the hazard level, not by preference.

A dynamic balancing valve line listed in the Apollo Valves catalog.

Use it whenUse it on hydronic heating and chilled water circuits to hold design flow through each branch as the system's pressure shifts, instead of chasing balance manually.

Two further categories in the Apollo Valves catalog.

Use it whenMixing valves for tempering domestic hot water to a safe delivery temperature; check valves wherever backflow into a pump or branch would cause a problem.

Three press systems alongside the threaded and flanged catalog. Apollo Press is described as a heat-free method for joining copper tube, PowerPress as a carbon steel press product line for schedule 10 to 40 steel pipe, and SmartPress as a stainless steel press connection system. Each includes both fittings and valves.

Use it whenReach for press when you cannot get a hot work permit or you need the crew to move faster than soldering or threading allows. Match the system to the pipe: copper to Apollo Press, carbon steel to PowerPress, stainless to SmartPress.
