Product Description

RESILIENT SEATED GATE VALVE Flanged type, DN40-300

Connection: Flanged to EN 1092-2, BS4504, ASME B16.10, AS4087
Working pressure: PN10/PN16/PN25
Temperature range: O 'C ~ 80C
Fusion bonded epoxy coating
Completely free and full bore self ciearning & low pressure loss.
Both inside & outside coated with epoxy resin powder.
O-ring bonnet gasket wraps each bolt to prevent corrosion.
Bolts sealed with hot met
Clockwise closing (CWC) as standard.
With rubber dust cover
4 o-rings on stem (total 6 o-rings in bonnet).
The upper 3 o-rings can be replaced online under pressure when valve fully opened.
Thrust washer - Brass material, to get more reliable strength and long service life
Body/bonnet connection

Bonnet gasket fits into a recess in valve bonnet preventing it from being blown out by pressure surges.

Bonnet bolts are in Galvanized carbon steel SS304 upon request
Liner Sealing face - get better sealing & lower closing torque.
Position "A" :

Most factories' design is the same lever to the sealing face, while when the valve closed, the increasing inlet pressure will push the disc shift and press to the valve body, which will cut the disc rubber of position "A" during long term use.
We aware this design defect; and innovate the current deisgn to avoid such hurt, thus enlarge the disc service life.
