Factory wholesale Pneumatic Needle Valve Flow Control - Rack and Pinion Ball Valve – Hankun Detail:
Product Introduction
Product Advantages
Double Block And Bleed:
This safety feature eliminates the buildup of pressure due to high pressure media trapped in the valve ‘s body cavity, even while the valve is in the fully closed position. Additionally, secondary graphite body seals and flexible graphite packing prevents leakage through the body joints and stuffing box, respectively.
Internal Trunnion Design:
Upper and lower bearing plates hold the ball in place, preventing the ball from floating axially and avoiding excess load on the seats. External trunnion design is available in certain sizes.
Double Seals On Body Joints:
Primary elastomeric seals ensure zero leakage in standard operating conditions. Secondary graphite seals ensure proper body joint sealing in extreme temperature scenarios.
Pressure Energized Stem Packing:
Our proprietary energizer ring, located above the primary o-ring stem seal, provides insurance in the rare event that the O-ring is damaged by using the media pressure to create an upward compressive force on the packing. This upward force on the packing combined with the downward compressive force created by tightening the packing gland results in a larger net compressive force on the packing and better seal than atypical packing design.
Valve Position Indication:
Clear stamping on the outer diameter of the mounting flange identifies the open or close position of the valve based on the stem key orientation.
