316 Stainless Steel Direct-Acting Pressure Reducing Valve – Z-Tide Industrial RET Series
The Z-Tide Industrial RET Series is a precision direct-acting pressure reducing valve designed to provide stable downstream pressure control for water, air, gases and compatible industrial fluids. Manufactured from 316 stainless steel with a balanced piston and diaphragm design, the RET Series maintains accurate outlet pressure despite normal inlet pressure fluctuations. Available in threaded BSP sizes from ½" to 2", with optional NPT or BSPP (G) threads, these valves are ideally suited to industrial water systems, reverse osmosis (RO) plants, compressed air installations and demanding process applications.

Manufacturing quality
Manufactured using heavy-duty 316 stainless steel with precision-machined internal components, the Z-Tide Industrial RET Series has been engineered for reliable long-term pressure regulation in demanding industrial environments. The balanced piston and diaphragm design automatically maintain a stable downstream pressure despite normal inlet pressure fluctuations, while the UH-ring sealing system provides excellent sealing performance, rapid response and long service life. The supplied stainless steel pressure gauge allows continuous monitoring of outlet pressure, and the protected adjustment mechanism on larger valve sizes provides secure pressure setting for industrial installations. Optional Duplex stainless steel construction, higher pressure adjustment ranges and working pressures up to 40 Bar are available for specialist applications.
Ordering information
