Non-flowing pilot valve
Size: 1"- 12"
Class: 150 lb -2500 lb
Temperature: -29 - + 260 C
Codes and Standas: API527; API 526; ASME VIII

Performance

The allowable tolerance of the set pressure ≤ ± 3% of the set pressure

Overpressure: ≤ 10% of the set pressure

Blowdown: ≤ 10% of the set pressure

Tightness: The valve have good seat tightness, conforms to API Std 527

Features

The soft seat design provides good seat tightness before and after each relief cycle

The system can be operated nearer set pressure without valve leakage

No more overpressure required for full lift of main valve

Proper valve operation and lift are unaffected by back pressure

Adjustable blowdown

Non-flowing pilot reduces product loss and environmental pollution

Quick simple verification of set pressure while valve remains in service
