Features

Series FSB 26 ball valves offers rugged and strong flow solution for hydraulic, chemical, steam, and oil/gas applications. Series FSB 26 is fire-safe tested for high pressure up to 6000psi (Class 2500). It is equipped with fire-safe design package and mounting pad design. Customers are often amazed by the extra weight of FSB 26 Fire-Safe Ball Valve, comparing with other conventional 2-pc ball valves. To maintain smooth valve operation and leakage- free condition, Series FSB 26 is constructed with thick body wall and ultra-strong parts to against high pressure usage.

The fire-safe design package includes: fire-safe lip, anti-static device, and sealing parts. The fire-safe lip is machined perfectly to fit the valve ball, so that in the case of fire and the ball seat has been decomposed, the firesafe lip come into contact with the ball. Eventually, a new metal-to-metal seal is formed. The new seal ensure the continuous valve operation after the event of fire. Anti-static device is used to discharge electric charges built up by valve operation. With small metal ball and spring inserted on the stem, the charges are grounded and prevent sparks caused electric charges. In Series FSB 26, instead of using PTFE for the sealing elements, graphite is used to prevent high heat condition. For other sealing material and special applications, please consult with DIE ERSTE representatives.

Series FSB 26 ball valves are also equipped with standard blowoutproof stem design gives a safer valve use environment when undergo unexpected events. The stem is inserted from inside of the bore, and locked from above with gland nut, to prevent stem shooting out during accidents. Also, the double-D shape stem design provides the easiness of lever mounting. The self-adjusting stem and packing assembly automatically adjusts with valve changes caused by thermal effects.
