MAIN FEATURES

Fire-SaFe Test
Approved trunnion ball valves are designed in accordance with API 607 & API SPEC 6FA. When non-metal seats are destroyed in a fire, the medium pressure push the upstream seat into the ball to cut off the line fluid and prevent internal leakage due to a secondary metal-to-metal seals. When the first soft seal is damaged, body, bonnet, stem-gasket can reach sealing function and prevent external fluid leakage.

Double body Gasket
All trunnion ball valves are equipped with two body gasket. The first body gasket is in soft material and the second in graphite (if not otherwise required), this combination assures the best seal characteristic in whatever corrosive service as well give fire safe design.
ANTi-static device In order to prevent static electricity which may light the fluid, static-conduction spring is set between the stem trunnion and the ball.

AnTi blow-ouT prooF STem
The stem is designed with integral T-Type shoulder to provide blow-out proof effectively. The design assures that the stem can not be blown out of the valve in the case of the packing being removed while the valve is under pressure.

CONTROLLED STEM & STUFFING BOX FINISH
Stem and stuffing box finish machining is a key point of control. The stem is made by cold rolling and stem surface finish is controlled by Ra=0.4, which can reduce friction for stem moving and ensure the seal. The stuffing box surface is controlled within Ra=1.6 for better sealing performance.

SOLID BALL
The solid ball used by FANGYUAN provides straight through flow and real full-port performance characteristics. Hollow ball or cored cavity ball are not used for products.
BALL SEAT ALIGNMENT
Stem/Flange mechanical stops ensure control and precise alignment over ball rotation.

LONGEVITY OF LIFE
Special consideration was devoted to the attainment of enhanced life and operation of our valve throughout design, development, testing and manufacturing stages. Valve designs combined with the selection of advanced materials are such that long periods of inactivity should not affect the operations of efficiency.

FLOW CAPACITY
Valve design allows for high flow capacity in liquid or gas services regardless of whether the media is clean or dirty. Full port valves allow for pigging and ensure maximum flow capacity.

FIELD REPARAIBLE
Simple user friendly design allows for quick and easy part replacement requiring minimal"Down Time".
EMERGENCY SEALANT INJECTION
For 6" full port and larger each valve is supplied complete with emergency stem sealant injection feature.

INSPECTION AND TESTING
Every valve is subjected on routine base to different non-destructive testing, like the dye penetrant test on butt weld ends, on all hard faced and cladding areas. Non-destructive test are also carried out on the critical areas as defined by ANSI B. 16.34.
Optional examinations like:
Radiographic
Magnetic particicles
Ultrasonic

MARKING AND IDENTIFICATION
Each valve is identified on proper name plate and on valve body as required by MSS- SP 25, B 16.34 Name plate carries all information on rating, size, valve body and trim material, customer tags. On body, marking includes material designations (per ASTM) and heat code and of course the trade mark.
