4 HHO 1/4" KYNAR CHECK VALVES WATER4GAS FASTEST SHIP

The Apollo 62-100 series stainless steel ball cone check valve with female National Pipe Taper (NPT) threads on both ends is a class 125 valve used for restricting flow to one direction. It has a spring-loaded ball check cone made of reinforced polytetrafluoroethylene (RPTFE) for fast seating action that is center-guided so that radial alignment is not needed, and it sits against the seat of the valve to block reverse flow. The straight-through flow minimizes velocity change. This check valve's body is made of American Society of Testing and Materials (ASTM) A-351 cast stainless steel for longer life in corrosive environments. This valve has maximum pressure ratings of 400 pounds per square inch (gauge) (psig) for cold working pressure (CWP)and 125 psig for steam working pressure (SWP), and a cracking pressure of 0.5 psi. It has female NPT threads on both ends for connecting to male threaded pipes with tighter seals than straight threads. This class 125 check valve is suited for applications in corrosive environments, including chemical processing, pulp, paper, and other process industries, and meets standard Manufacturers Standardization Society (MSS) SP-80 for quality assurance. Class is a standard relating to tolerance, construction, dimension, and wall thickness, but it is not a direct measurement of maximum working pressure. Check valves have two ports and restrict the flow of fluids and other loose materials through a pipe or passageway to one direction. Flow enters through one port and exits through the other, closing when flow reverses or stops. Two common types of check valves are ball cone valves and swing check valves. A ball cone valve utilizes a spring-loaded ball seated against a cone-shaped interior surface to stop the flow of fluid in a forward direction, and a swing check valve has a movable disc on a hinge to block reverse flow. Check valves are rated by their cracking pressure (the minimum upstream pressure required for the valve to operate), and they are used in various water, gas, air, and steam lines. Apollo manufactures ball, mixing, and relief valves, actuators, water gauges, marine fittings, heating and plumbing products, and backflow prevention devices. The company, founded in 1928 and headquartered in Matthews, NC, meets International Organization for Standardization ISO/IEC 17025:2005 and makes products that meet ISO and American National Standards Institute (ANSI) standards.

Mazzei® Injectors are high-efficiency, venturi-type, differential pressure injectors with internal mixing vanes. When a sufficient pressure difference exists between the inlet and outlet ports of the injector, a vacuum is created inside the injector body, which initiates suction of a liquid or gas through the suction port.How a Mazzei® Injector WorksWhen pressurized water enters the injector inlet, it is constricted toward the injection chamber and changes into a high-velocity jet stream. The increase in velocity through the injection chamber results in a decrease in pressure, thereby enabling an additive material to be drawn through the suction port and entrained into the water stream. As the jet stream is diffused toward the injector outlet, its velocity is reduced and it is reconverted into pressure energy (but at a pressure lower than injector inlet pressure).Mazzei® Injectors are extremely efficient. They operate over a wide range of pressures and require only a minimal pressure differential between the inlet and outlet sides to initiate a vacuum at the suction port.Special Features NEW INTERNAL VANES are positioned to maximize injector efficiency, suction capacity, and mixing capabilitiesTROUBLE-FREE OPERATION with no moving parts PROVEN PERFORMANCE with years of expected serviceNo electrical connections neededCan run dry with no problemsConsiderable cost savings versus other injection methodsSafe to use as the chemicals are under vacuum, not pressureConstant injection of assures UNIFORM DISTRIBUTION OF MATERIAL LONG PRODUCT LIFE constructed of strong, chemical-resistant PVDF (KYNAR® and HYLAR®) with a 5-year warranty or POLYPROPYLENE with a 1-year warranty.ISO-R (BSPT) threads available in PVDF modelsPVDF advantages:PVDF is an advanced thermoplastic that is superior to other types including PVC, Polypropylene, & PolyethyleneStronger/Higher pressure and temperature handling capabilitiesResistant to ozoneGreater chemical resistance / Resistant to Chlorine, Sulfuric and Nitric AcidsAbrasion and wear resistantSunlight (UV) resistantHow to size your Injector?
