Product Overview
The HOKE 7312002 is a precision-engineered instrumentation valve from HOKE Incorporated, a globally recognized manufacturer of high-integrity fluid control components for process, pneumatic, and hydraulic systems. Designed around a robust needle valve working principle, the 7312002 provides accurate, repeatable flow regulation and reliable bubble-tight shutoff in low-to-medium pressure instrumentation circuits. Its compact bar-stock body construction and fine-thread stem geometry allow operators to meter gases and liquids with exceptional resolution, making it a preferred choice for analyzer systems, sampling panels, gauge isolation, and pilot-duty pneumatic control lines where leakage integrity and long service life are critical.

Engineering Features & Advantages
- Precision Performance: Fine-pitch threaded stem and non-rotating vee-tip design deliver smooth, linear flow control with high resolution, enabling accurate metering of low-flow instrumentation and pneumatic signals.
- Leak-Tight Integrity: Metal-to-metal or soft-seat shutoff geometry ensures bubble-tight isolation, protecting sensitive transmitters, analyzers, and gauges from process contamination.
- Industrial Reliability: Built for continuous operation under severe industrial conditions, with a bar-stock 316 stainless steel body that resists corrosion, vibration fatigue, and thermal cycling.
- Direct Fit Replacement: Exact dimensional and functional compatibility with original OEM standards, allowing drop-in replacement without modification to existing tubing, manifolds, or panels.
Typical Industrial Applications
The HOKE 7312002 instrumentation valve is widely deployed in oil and gas sampling and analyzer systems, chemical and petrochemical process panels, pneumatic control and instrument air circuits, hydraulic test stands and calibration benches, and power generation instrumentation where precise isolation and flow regulation of gases or liquids is required.
