Product Description
Nai-Lok UHP 1 4 Male Metal Face Seal Manual Diaphragm Valve Low Pressure 1MPa Ultra High Purity Special Gases 20.5 Mpa Diaphragm Valve for Gas Distribution 3000psi SS316 Stainless Steel Diaphragm Valve
The structure of the diaphragm valve is very different from that of ordinary valves. It is a new type of valve and a special type of block valve. Its opening and closing parts are a diaphragm made of soft materials, which separates the inner cavity of the valve body from the inner cavity of the valve cover and the driving parts. Now it is widely used in various fields. Common diaphragm valves include rubber lined diaphragm valve, fluorine lined diaphragm valve, unlined diaphragm valve and plastic diaphragm valve.
The NAI-LOK Ultra High Purity (UHP) Diaphragm Valve is engineered for high-pressure, ultra-clean gas and fluid control in semiconductor, pharmaceutical, and specialty gas industries. Available in manual and pneumatic actuator configurations, this valve delivers exceptional sealing performance, corrosion resistance, and contamination-free operation at pressures up to 20.5 MPa (3000 psi).
Ultra High Purity (UHP) Design - Ideal for semiconductor gas delivery, chemical processing, and high-purity applications with minimal particle generation.
High-Pressure Capability - Rated for 20.5 MPa (3000 psi), ensuring reliable performance in demanding environments.
