More than 40 years managing temperatures

Penta Srl is a private owned company that started in 1977 the production of Metal Seated Ball Valves for extreme conditions as high temperatures (up to +700°C), Low temperatures (down to -196°C) and abrasive or dangerous services. During the years, Penta has developed many proprietary technologies: the unique self lubricating PENTAFITE seat material and in-shop fabricated special high pressure resistant Grafoil gaskets. We cooperate with our Customers all around the world (more than 80% of our production is exported outside Italy) to identify the best model and construction that better meat actual working conditions to maximize valve life and update any product to the most modern technologies and solutions. Penta keeps all information related to any product available for 20 years as like as spares availability. Moreover our workshop is always available for in-shop maintenance of our products.The Penta Srl range of products includes:

  • AP series : a medium temperature and pressure valve (up to 350°C in class ANSI900 or PN160) with aggressive price;
  • WSS series: a wafer split body ball valve used on dirty services (up to 400°C)
  • SAT model, the best design of PENTA to solve the widest range of use between -100° and +700°C with pressures up to ANSI2500 and many different metal seats availability, including PENTAFITE technology.
  • SAT Crio model is the extension of SAT model down to -196°C by the use of polymeric seats and special valve arrangement that guarantee tightness and operability at any temperature.
  • SAT3 model is an evolution of the SAT with the addition of two Scraper Rings inside and outside the seats allowing the cleaning of ball surface during valve operation, the protection of the seats from abrasion and the reduction of dirt filling body cavities.
  • MULTIPORT basing on a trunnion mounted construction Penta can manufacture a range of 3-way metal seated ball valves with “L” port or “T” port.

Penta has obtained ABS (American Bureau of Shipping) Approval for use on LNG (liquefied natural gas) vessels carrying. 100% of all our valves are fully hydrostatically body tested at 1,5 times the maximum rated pressure and then hydrostatically seat tested at 1,1 times and 6 bar seat tested with air to check perfect tightness exceeding ANSI/FCI 70-2 Class VI. The company is ISO 9001 and ISO 14001 certified.

Specialized in valves for critical conditions (high and low temperatures, abrasive and dangerous services)
