BNH Series Integral Bonnet Needle Valves

BNH Series Integral Bonnet Needle Valves

Integral bonnet needle valves are a type of control valve commonly used in various industries to regulate and control the flow of fluids. These valves feature a compact design that integrates the bonnet and the body into a single unit, providing a robust and reliable solution for fluid control applications.The primary purpose of integral bonnet needle valves is to precisely control the flow rate of fluids, especially in situations where a high level of accuracy is required. They are often used in systems that handle high-pressure or high-temperature fluids, such as in oil and gas, chemical processing, power generation, and other industrial applications.

BNH Series Integral Bonnet Needle Valve Features:

• One-piece forged body
• Easy external adjustments by packing nut.
• Compact design.
• Handle color options are available
• Leak-tight performance testing for every valve with nitrogen at the maximum working pressure.
• Maximum working pressure: BNH Series-Stainless steel: 5000 psig (345 bar)
• Working temperature:PTFE:-65°F to 450°F（-54°C to 232℃）PEEK:-65°F to 500°F（-54Cto 260°℃）
