SHOK BLOK Pressure Limit Vlv, 1/4" QC

The Hydronix SHOK BLOK Pressure Limiting Valve protects sensitive point-of-use water equipment by capping incoming line pressure at 60 PSI. Fitted with 1/4" quick-connect tube ports on both the inlet and outlet, it installs easily into reverse osmosis and drinking-water systems that use 1/4-inch tubing, requiring no special tools to splice into the line and no threaded fittings to seal.

Many homes and buildings supply water at pressures well above what delicate RO components and filters are designed to handle. Excessive pressure can stress membranes, housings, fittings, and storage-tank bladders, leading to leaks, premature failure, and even sudden ruptures. By holding downstream pressure to a safe 60 PSI, the SHOK BLOK shields the entire system and helps it perform consistently regardless of fluctuations in the household supply, which is especially valuable in areas with high municipal pressure or on systems fed by a booster pump.

• Limits downstream pressure to 60 PSI
• 1/4" quick-connect tube inlet and outlet
• Tool-free installation into 1/4" tubing runs
• Protects RO membranes, housings, and fittings
• Guards against pressure spikes and water hammer
• Hydronix Water Technology quality

Beyond steady-state protection, a pressure limiter also helps absorb the spikes and water-hammer effects that occur when valves open and close quickly, smoothing operation throughout the system and reducing fatigue on tubing and connections. The quick-connect ports grip standard 1/4-inch tubing securely and release cleanly when needed, making the valve simple to add to a new build or retrofit into an existing setup in just a few minutes. Positioning the SHOK BLOK on the feed line ahead of the RO system ensures every downstream component sees only the regulated pressure. For dependable pressure control in compact water-treatment installations, the Hydronix SHOK BLOK 60 PSI limiting valve is an easy, effective safeguard that can prevent costly leaks and damage.

Install the SHOK BLOK with attention to flow direction and verify that all quick-connect joints are fully seated before pressurizing the system. As inexpensive protection against the leaks and component failures that high pressure can cause, this pressure-limiting valve is a worthwhile addition to virtually any RO or point-of-use installation fed by an above-spec supply. Small, affordable, and easy to fit, it is cheap insurance for a system worth protecting.
