Types of Instrumentation Valves:
Needle Valves – For precise flow control and throttling applications
Ball Valves – Quick shutoff, two-way and multi-port configurations
Manifold Valves – Used in pressure and differential pressure transmitter installations
Check Valves – Prevents backflow in instrumentation and control systems
Globe Valves – Designed for accurate flow regulation
Gauge Valves – Used for pressure gauge isolation and calibration
Double Block & Bleed (DBB) - valve provides dual isolation and pressure release in a compact design, ensuring safety and leak prevention in high-pressure applications.
Cryogenic Service
Instrumentation Valves can be designed for cryogenic applications down to -196°C, with special materials and extended bonnets to prevent freezing issues. If required by the customer, cryogenic testing is performed to verify performance in extreme conditions, ensuring low operating torque, leak-tight sealing, and emissions control.
