Features & Benefits
Non-Rotating Needle Tip
Hardened Vee-point tip does not rotate against seat, preventing scoring and ensuring bubble-tight shutoff through thousands of cycles.
Blow-Out Proof Stem
Retention collar prevents stem ejection under pressure during packing adjustment or gland removal, protecting personnel.
Union Bonnet Option
Union bonnet allows packing replacement and stem service without removing valve from the process line.
One-Piece Barstock Body
Machined from solid SS316 eliminates porosity and provides superior fatigue resistance in cyclic pressure and vibration service.
Panel Mountable
Square body and lock nut option allows secure mounting on instrument panels and gauge boards.
