NATO Supply Class 4820 is a classification within NATO Supply Group 48, which is specifically for valves. More specifically, NATO Supply Class 4820 is for nonpowered valves.
Valves are mechanical devices used to control the flow of fluids (liquids, gases, or slurries) through a system of pipes or tubes. They are essential components in various industries, including manufacturing, oil and gas, water treatment, and many others.
Nonpowered valves, as the name suggests, do not require external power sources to operate. They rely on manual or mechanical means to control the flow of fluids. This can include hand-operated valves, lever-operated valves, or valves that are actuated by mechanical systems such as springs or diaphragms.
NATO Supply Class 4820 includes a wide range of nonpowered valves, such as gate valves, globe valves, check valves, ball valves, butterfly valves, and many others. These valves are designed to meet specific requirements for different applications, including controlling the flow rate, regulating pressure, preventing backflow, or isolating sections of a system.
The classification of valves into NATO Supply Groups and Classes helps standardize the identification and categorization of these essential components for military and defense purposes. It ensures that the right valves can be easily identified, procured, and used in various military operations and equipment.
If you need more specific information about a particular type of nonpowered valve within NATO Supply Class 4820, please let me know, and I'll be happy to assist you further.

- What is a Stop And Stop Check Valve? 12 Items
- A Stop And Stop Check Valve (VALVE,STOP AND STOP CHECK) is a combination of two valves, one a stop valve, the other a stop check valve, either in the same body, or in separate bodies bolted together, used to control the admission of feed water to a boiler, to prevent the return of water or steam from the boiler, and to provide a means of shutting off the feed line between the stop check valve and the steam drum or economizer.
- What is a Valve Rotary Plug? 21 Items
- A Valve Rotary Plug (PLUG,ROTARY,VALVE) is a cylindrical or tapered item with ports or segments designed to stop or control the flow of fluid in a VALVE, PLUG, or the like. It may have an integral stem for connection to a handle, lever, rotary actuator, or the like.
- What is a Directional Control Linear Valve Sleeve? 51 Items
- A Directional Control Linear Valve Sleeve (SLEEVE,DIRECTIONAL CONTROL LINEAR VALVE) is a cylindrical item with an opening throughout its length which may be of cylindrical or other cross-sectional shape. It has external grooves for fluid flow, and may have external packing grooves. This item provides internal porting for various inlet and outlet ports of a directional control linear valve.
- What is a Directional Control Linear Valve Slide? 47 Items
- A Directional Control Linear Valve Slide (SLIDE,DIRECTIONAL CONTROL LINEAR VALVE) is an item which may have a cylindrical or other cross-sectional shape, with recess areas on the periphery. It is designed to control the flow direction in a linear directional control valve by the selection of various inlet and outlet ports in a sleeve or the valve body. The slide reciprocates thus mating recess areas with the various ports in the sleeve or valve body. It may have an off (no flow) position.
- What is a Directional Control Linear Valve? 566 Items
- A Directional Control Linear Valve (VALVE,LINEAR,DIRECTIONAL CONTROL) is a manually or power operated valve having three or more ports. The direction of the flow through the various ports is controlled by either one or more reciprocating slide(s) or spool(s) with recess areas which mate with ports in an integral or replaceable ported sleeve, or one or more poppet(s). It is designed to change the direction of fluid flow from one valve port to another. An off (no flow) position is not a flow pattern. The valve is designed to actuate various components of a fluid system. A power operated valve may have a manual override. For items which stop, start, or change the flow of fluid, see: VALVE, SOLENOID. Excludes VALVE, PLUG.
