INVESTMENT CAST BODY CONSTRUCTION
1. PYRAMIDAL STEM WITH STEM SEAL
First stage of defense against leakage. The 45 degree slope of the
stem accompany by the stem seal effectively blocks all leak path from
forming during rotation.
2. V-RING STEM PACKING
Second stage of defense against leakage. Triple layers of V-Ring
Chevron packing expands side ways as it is being compressed,
blocking all air pockets thus preventing leak path. The grinding effect
of metal to PTFE contact.
3. GLAND
Made of stainless steel, equally distributes the compressive force
on the packing and the seal.
4. BELLEVILLE WASHER
Release stored compressive energy for automatic compensation
of seals due to wear and tear fluctuation of temperature and pressure.
5. LOCK SADDLE
Stabilizes the stem nut to keep it from loosening.
6. STEM NUT
Compress the entire stem system to enable blocking of leakage.
7. ANTI-STATIC DEVICE
Standard applied between stem and ball, stem and body.
