Product Title: J19H Pressure Gauge Needle Valve for Precision Control
Model: J19H

Product Overview

The J19H Pressure Gauge Needle Valve is designed to provide precise flow control while protecting pressure gauges from overpressure. Its needle-type design allows for fine adjustment of fluid flow, making it ideal for applications requiring accurate regulation. Suitable for temperatures up to 150°C and pressures up to 32MPa.

Key Features

1. Needle-Type Precision
   • Tapered needle ensures exact control over fluid flow to the gauge.
2. High-Pressure Capability
   • Rated for pressures up to 32MPa (4640 PSI) for demanding applications.
3. Gauge Protection
   • Built-in check valve prevents overpressure damage to the gauge.
4. Versatile Media Compatibility
   • Suitable for LPG, acid, steam, oil, and other non-corrosive fluids.

Detailed Description

1. Working Principle
The needle-shaped plunger moves vertically to control the flow area, allowing precise regulation of fluid flow to the pressure gauge. A built-in check valve prevents reverse flow and overpressure.

2. Construction & Materials

• Body: Stainless steel (SS316) for corrosion resistance.
• Needle: Hardened stainless steel for durability.
• Seat: PTFE for tight sealing.
• Check Valve: Stainless steel ball for reliable closure.

3. Installation & Maintenance

• Orientation: Install directly upstream of the pressure gauge.
• Maintenance: Regularly inspect the seat and needle; clean or replace as needed.

4. Applications

• Industrial: Process control systems, chemical dosing.
• Energy: LPG/CNG dispensing, fuel lines.
• Laboratory: Gas chromatography, analytical instruments.

Why Choose J19H?

• Precision: Needle design ensures accurate flow control.
• Safety: Protects pressure gauges from overpressure damage.
• Durability: Withstands high pressure and corrosive environments.
