- Features
- Series FSB 23 is 2-piece screw-in structure. It has been tested and approved for Fire-Safe Certification of API 607 4th Edition. To meet tough requirements of API 607 4th Edition, Series FSB 23 ball valve is able to sustain high pressure of 3000psi and still provide smooth operation. The blowout-proof stem is standard equipment for FSB 23.
The stem is inserted from inside the bore and will not shoot out under high pressure, and thus, provides safer working conditions. The fire-safe design package is consisted of three parts: fire-safe lip, antistatic device, and sealing parts. The fire-safe lip is precisely machined to match the ball. In the case of fire and the soft ball seat has been decomposed, the fire-safe lip act as a secondary seal with the floating ball. Anti-static device grounded charges built up by valve operation, and prevent explosion, especially with flammable fluid. Valve sealing parts can be selected from various materials: graphite, PEEK, DELRIN, and Nylon. Please specify the seat material before making any inquiries or purchases. For fire-safe purposes, graphite body seal and stem packings are used.
Series FSB 23 ball valve is equipped with thrust washer and gland nuts to achieve non-leak quality. The thrust washer not only prevents galling between stem and body, it is also considered as a secondary stem seal and reduces torque. The gland nut is tightly sealed to prevent leakage and act as the last guard. Series FSB 23 ball valve is accompanied with different choices of seat materials to choose from. FSB 23 can also be used in normal condition with a change of ball seat; it can be used like other conventional 2-pc ball valve.
