Valves

DistributionNOW provides one of the industry's most comprehensive inventories of valves in commodity and specialty materials, with numerous different designs and sizes depending on functions such as on-off service, throttling service, preventing reverse flow, pressure control, flow control, temperature control, level control, directional flow control and sampling. We are a proud member of the Valve Manufacturers Association of America.

Types of Valves by Operating Principle

DNOW offers a variety of valves that can start, stop or regulate the flow of a liquid, gas, or suspended solid materials, in volume, through a pipe, duct, etc., via a manual or automatic means with an internal closure element. From quarter-turn valves, to check valves, to multi-turn valves, to safety relief valves, we offer an extensive inventory with valve testing, design, field service and maintenance solutions.

Selecting the Right Valve

The main parameter concerned in selecting a valve or valves for a typical general services are:

Fluid to be handled type of valve and its material
Functional requirements type of valve used
Operating conditions both choice of valve type and constructional materials
Flow characteristics & frictional loss where not covered by functional requirements or setting additional specific/desirable requirements
Size of valve may affect the choice of the type of valve (e.g. - very large sizes have limited range of types)
Special requirements quick-opening, free-draining, control, temperature
