Butterfly Valve
High-Performance U-500 Series
Features
1. Water & lug bodies butterfly valve for bl-directional dead-end service are offered as standard in full ANSI Class 150 and 300 ratings.
The design of double offset sealing assure smooth low-torque operation and reduce seat wear. Extended neck length allows adequate insulation and is easily accessible for mounting actuators.
2. Valve has a disc stopper to prevent disc overtravel of disc, minimizing possible seat damage with extending the service life of valve operator.
3. The disc has been hydromechanically designed to maximize flow and minimize resistance, providing a high Cv valve. The disc is spherically machined and hand polished disc edge provides bubble-tight shut-off at minimum torque.
4. One piece through stem design achieves high strength and positive disc control optional mounting plate is available to international standard.
Non-lubricated, coated bearings securely support the stem and minimize bearing triction and operating torque.
5. Securing the butterfly disc to the valve shaft and permitting accurate disc closure for consistent sealing and positive shut-off.
6. V-Packings are designed to give excellent resistance to pressure and effective at both low and high pressures with little of no gland adjustment required. Gratoil packings are also available for high temperature applications and are standard on firesafe valve & metal seat.
7. All valve shall be tested for leakage at rated internal pressure and we can accomplish zero defects through a wide range testing process.
8. With a locking spring loaded, lever operator has directional pointer for valve disc position indication with easy-grip hasdle.
Seat Explanation
Soft Seat | Material PTFE & RTFE |
Blowout Proof Stem Design Lower Operating Torque Tight Shut-Off Bl-Direction Application Leakage Classs VI(Zero) |
|
Metal Seat | Material : 316L & Inconel |
Blowout Proof Stem Design Inherent Fire Safe Design Sultability for High Temperature Service Leakage Class IV, V |
|
Fire Safety Seat | Metal & Soft Seat |
Blowout Proof Stem Design Tight Shut-Off Bl-Direction Application Inherent Fire Safe Design Leakage Classs VI(Zero) |
|
During and after a fire, when the soft(Teflon) seat material has burned away, the metal seat actvates atomatically and prevents excessive flow. |
|
Non-Seat | |
Blowout Proof Design High Temperature Service Non-Seat or Tadpole Step Leakage Class II or III |
