Features & Benefits
Integral Block and Bleed
Two valves in one solid body eliminate adapter fittings and threaded connections, reducing potential leak paths by 60%.
Non-Rotating Needle Tip
Tip does not rotate against seat during operation, preventing seat scoring and ensuring bubble-tight shutoff for 100,000+ cycles.
Direct Transmitter Mount
54 mm centre-to-centre bolt pattern matches most DP transmitters, allowing direct mounting without impulse tubing or brackets.
Blow-Out Proof Stem
Stem retention collar prevents accidental ejection under pressure during packing adjustment or gland removal.
Panel Mountable
Square body and lock nut allow secure bulkhead or instrument panel installation.
