Hy-Lok's compact integral block & bleed valves are the ideal alternative to multiple instrument valve systems. Integral block and bleed valves reduce overall fluid system weight and height, providing fewer leak paths and reducing the risk of vibration damage.
Block and bleed valves are offered in a wide variety of end connections, body types, and valve technology. Rugged 316 stainless steel quarter turn handles facilitate low torque operation and rust resistance in offshore environments. Unique enclosed seats offer great process compatibility, restricting creep or distortion in service.
Hy-Lok's approach achieves high levels of seat integrity at both low and high pressures. Flexible configurability lends itself to a wide range of applications including block & bleed instrument isolation, pressure, level and flow measurement, instrument drain, chemical injection, and sampling. Instrument block and bleed valves are available in stainless steel, carbon steel, monel, titanium, duplex, and more. Double block & bleed valves are also available.
Integrally forged, one-piece double block and bleed assemblies for primary isolation of pressure, where the valve is directly
mounted to the vessel or process pipe.
Like the modular valves, Hy-Lok's monoflange valves are integrally forged and single body construction, offering a lighter weight
and smaller footprint; perfect when space is critical.
Allows the injection of chemicals and other media into the process stream. Incorporating a one-way check valve
(opens / closes for injection), this chemical injection valve effectively eliminates process fluid outflow.
