INBALL valves are manufactured using revolutionary hydraulically controlled valve technology. The basic concept is NMMP (No Mooving Mechanical Parts). This is a key indicator in extinguishing systems that ensures reliability.
INBALL valves are registered by Underwriters Laboratories (UL) and are Factory Mutual (FM) certified. Owned by Lloyd's Registry, American Shipping Bureau (ABS) and Det Norske Veritas
approval. In addition, these valves are also certified by the Russian Shipping Register and have a certificate of conformity for ГОСТ Р 51052-2002.
All valves are designed for a pressure of 2.1 MPa. The valves are manufactured in sizes from 1 1⁄2 "to 12" (40 mm to 300 mm). It is possible to order all possible pipe connections - flange, threaded, etc. As a rule, the flanges of INBALL valves are made of wrought iron. The housing is made of epoxy coated steel. Other materials can be ordered on special order: stainless steel, bronze, nickel-aluminum-bronze and titanium alloys. Other protective coatings can also be ordered on special order, eg. thickened epoxy layer or Halar.
The valve control pipes are made of stainless steel and chrome-nickel brass. In addition, chromium-nickel bronze and titanium are used.
