Establishments primarily engaged in manufacturing fluid power valves are classified in SIC 3492: Fluid Power Valves and Hose Fittings
SIC 3593 applies to FLUID POWER CYLINDERS AND ACTUATORS.
SIC 3594 applies to FLUID POWER PUMPS AND MOTORS.
This classification covers establishments primarily engaged in manufacturing hydraulic and pneumatic valves, hose and tube fittings, and hose assemblies for fluid power systems.
According to the NFPA, fluid power is energy that is transmitted and controlled through a pressurized fluid--liquid or gas. Fluid power valves regulate the liquid or gas as it moves through valves, hoses, and fittings.
NAICS Code 332912 (Fluid Power Valve and Hose Fitting Manufacturing)
In 2000, the value of shipments within the fluid power industry totaled $6.7 billion.
This category covers establishments primarily engaged in manufacturing industrial valves.
SIC 3663 covers makers of RF power amplifiers
Included in the total fluid power market are fluid power valves and fittings as well as hydraulic and pneumatic pumps, cylinders, rotary actuators, motors, filters, hose accumulators, air preparation accessories, stationary compressors, and other products
The leading states for the production of fluid power valves and hose fittings are all east of the Mississippi and include Connecticut, Minnesota, Texas, New Jersey, Michigan, and Ohio.
yes it has 2 valves , one for fluid, one for waste production
The function of a check valve is to prevent backward flow of liquid by closing. The check valves close by using fluid pressure. They are two port valves, which means there is an opening for fluid to enter and one for fluid to escape.
