Description
Our SL-HD04MN Series manual diaphragm valves are engineered for high-purity and high-pressure applications up to 3000 psi. Constructed from corrosion-resistant SS316L stainless steel, each valve features electropolished and BA-finished internal surfaces, making them ideal for critical gas or fluid control in demanding environments.
All ports are equipped with 1/4" Female NPT (FNPT) connections for secure and standard thread compatibility.
