Valves are used in pipe systems to control flow of the liquid. They are produced in various forms and from different materials. Adequate choice of valves is very important in order to obtain a system that is maximally secure and efficient, has affordable price and lasts for a long time.

Proper functioning of all components is important in complex fire protection systems that protect lives and property. Valves used in fire protection systems are not an exception, NIBCO fire protection valves are certified by UL/FM, which guarantees quality and reliability.

Underwriters Laboratories Inc. (UL) is independent, non-profitable organization that tests security of products and issues certificates. For more than a century it has been testing safety of products intended for general public. Each year, more than 16 billion UL labels are put to products all over the world.

Factory Mutual Research Corporation (FMRC) is an agency that tests insurance companies. Factory Mutual Research works with commercial and industrial clients for the purpose of solving issues via unique interaction by our three work units: Standards, Research and Certification of products (Approvals). Results of the research set new standards that improve loss prevention practice and aid in development of new products. Besides that, producers use services of independent test laboratory Factory Mutual Research in order to receive approval that confirms reliability of their products and services.

A product with UL and FM certificate is guaranteed for supreme quality and reliability.

NIBCO appeared on the valve market in 1963, via acquisition of “SCOTT VALVE” plant in Detroit, U.S. state of Michigan. By entering the valve market, NIBCO commenced production of gate valves, globe and check valves in its foundry in Nacogdoches, the U.S. state of Texas.

In 1975 a new plant for production of gate valves, globe and check valves from cast iron was built in Blytheville, the U.S. state of Arkansas.

Acquisition of the plant for production of ball valves with flanged end “LUNKENHEIMER (QUARTROL)” was completed in 1988.

In 1991 NIBCO took over the plant “THE (TRUELINE)” and commenced production of ball valves with flanged end SPLIT BODY (FULE BORE), classes 150 up to 600.

Today NIBCO is one of the world’s biggest valve producers and it also owns two foundries and several manufacturing facilities for production of all types of valves. You can count on wide range of valves (from 1/4” (6mm) up to 36” (900mm)) designed to ease your work.

When you say NIBCO, you can be certain in three things: quality, short delivery deadline and technical support.

Valves are designed to conduct four basic functions:
  1. Commence and stop flow (isolation)
  2. Regulate (throttle) flow
  3. Prevent flow reversibility (reverse flow)
  4. Regulate or release flow pressure
