Product Description:
Standard design features include:
Body and trim material – Body materials are ASME material grades WCB,
LLC CF8M, with Stainless Steel Trim.
QDV Quality Procedures: Every valve is tested and inspections are performed throughout the production process.
Encapsulated Body Seals: With fully encapsulated body seals there is no opportunity for seal movement or slippage, thereby improving sealing.
Ball Position Indicator and Blowout Proof Stem Features: The stem is designed with a double flat shape at the top of the stem to indicate ball position. PBV valves blowout proof stem feature is accomplished by the use of a lower stem collar design.
Bubble tight sealing: Bubble tight sealing is achieved by the use of two rigid seats firmly secured in the valve body on either side of the ball.
Bi-directional Sealing: With the bi-directional sealing design, either end can be installed up stream with out compromising the integrity of the seal.
Equalized Cavity Pressure: the pressure equalization hole at the top of the ball combined with the seat design are both engineered to maintain the pressure balance in the line and body cavity while the valve is in the open position
