Stafsjö valves protect installations

September 2019 Valves, Actuators & Pump Control

When it comes to industrial fire protection systems, reliability is essential. The system, which is often on constant standby for long periods, should be able to respond immediately and extinguish possible ignition sources to prevent fires and dust explosions.

Firefly, one of the world’s leading suppliers of spark detection and fire and dust explosion protection systems uses Stafsjö valves to protect installations worldwide.

For more than 30 years, Firefly has been using Stafsjö’s valves in their fire protection systems because the valves are robust, reliable, and deliver performance when required. It is a dependable product that provides the quality that customers require. With a closed knife gate valve, fires and dust explosions can be prevented, which enhances the levels of fire safety for users.

Stafsjö’s HG isolation valve has a through-going gate for reliable shutoff performance, independent of pressure direction. Its ability to cut through static media columns also serves its purpose well. Superior flow characteristics enable it to act as a part of the pipe system without affecting the process flow. Stainless steel metal seats extend the service life and offer low friction to achieve ultra-fast isolation time. Sometimes the valve is also supported by a pressure tank to speed up the shutoff time.
