3-Way Ball Valve has two kinds of flow passage pattern, it can be Floating Type or Trunnion Mounted Type
Type L (3-way and 2-port)
Type T (3-way and 3-port).
The correct option is subject to end user's application.
 
1. Blow-Out Proof Stem
For the purpose of preventing the stem from flying off resulting in abnormal rising of the inner pressure of valve, shoulder is fixed at the lower part of the stem. Additionally, in order to prevent leakage resulting from burnout of packing set of the stem in a fire, thrust bearing is set at the contact position of the shoulder at lower part of the stem and valve body. Therefore an inverse seal seat is formed which will prevent leakage and avoid accident.
 
2. Fire Safe Design
SBV 3-Way Ball Valve fire safe is designed in compliance with API 607-4th, API 6FA and BS 6755 Part 2. Each possible leakage parts between body and ball, middle flange, body and stem is designed as metal-to-metal contact, when non-metal resilient seats are damaged in a fire or unusual temperature increasing, the upstream medium pressure push the ball into the downstream metal seat lip to cut off the line fluid and prevent the internal leakage dueo to a secondary metal-to-metal seals.
 
3. Anti-Static Design
In order to prevent friction among ball, stem and PTFE that generates static electricity which may light the combustibles and explosives that cause an accident, in this ball valve, static-conduction spring is set between the stem and the ball, the stem and the body. Thus static electricity is conducted to ground and system safety is secured.
 
4. Low Operation Torque
The self-lubricated bearings are installed at the friction of stem, resulting in wear resistance, flexibility of operation and low torque.
 
5. Various Operation Types
The valve top working flange is designed according to ISO 5211 (if design is allowed),which is convenient for connection and change its operation types. The common operation types are manual (Lever/Gear Box), electrical, pneumatic and pneumatic/hydraulic.
