The PPIEY Straight Pressure Limiting Valve is a dedicated in-line pressure regulating fitting for domestic water purification systems. Featuring dual push-in ports in a straight configuration, it stabilizes pipeline pressure, protecting equipment and tubing from high pressure impact.
- Product Introduction
Yuyao Eshiong Pipe Fittings Technologies Co., Ltd. is one of the leading manufacturers and suppliers of straight pressure limiting valve in China. Please rest assured to wholesale bulk durable straight pressure limiting valve from our factory. All customized products are with high quality and competitive price. Also, free sample is available.
The valve body is marked with an arrow to indicate the correct water flow direction for proper installation. It is designed for use with non-corrosive clean water only.
Available in two common sizes to match mainstream domestic water system configurations: 1/4"" and 3/8"" tube connections. The valve is typically installed in-line on the inlet or outlet pipelines of RO machines, pre-filters or water dispensers. Its straight design allows for installation in confined spaces where compact in-line fittings are required, protecting internal components such as membranes, filters and tubing from damage caused by fluctuating water pressure.
