VALVULA BOLA
ESPECIFICACIONES TECNICAS
LOW TORQUE FOR EASIER OPERATION PARALLEL FLAT STEM HEAD

shows valve open or closed position

easy to manually operate and cost saving for actuation

PREVENTION OF EXTERNAL LEAKAGE TO ATMOSPHERE

STOPPER

controls opening and closing range
ACTUATOR MOUNTING PAD

chevron packing provides maximum sealing effect

METAL TOMETAL CONTACT

prevents external leakage

easy to mount an actuator without dismantling valve

V YV AL AL
thrust bearing guarantees perfect sealing even in low pressure grounds stem to provide continuity for anti-static protection
PRIMARY STEM SEAL MACHINING ACCURACY AND ULTRA SMOOTH SURFACE FINISH ANTI - STATIC DEVICE

-provide smooth actuation -resist wear

LONG

- LIFE STEMBEARING

BLOWOUT - PROOF STEM

the internally backseated stem provides blow - out proof safety

guarantees precise operation and long file
REINFORCED PTFE SEAT

DYNAMIC SELF - ADJUSTING CENTER - LINE

assures bubble - tight sealing and ball surface protection

tolerance between body and seat allows the ball to maintain its position

TWO

-not special tool required -stud bolting makesmaintenace and repair easy
