What is 2-Valve Manifold Block & Bleed?
A 2-way manifold valve is constructed as a single block featuring an isolation valve and a calibration/vent (bleed) valve in combination. These valves typically come with male or female screwed inlet and outlet ports. The block valve is indicated by a blue handle, while the bleed valve is distinguished by a red handle. Typically, they are manufactured using stainless steel and equipped with standard PTFE valve packing.
Featuring PTFE packing, these manifolds exhibit the ability to withstand pressures reaching up to 6000 PSI at 200°F or 4000 PSI at 500°F. For higher temperatures, Grafoil Packing is employed. 2-way valves are available as in-line type, L-shaped, or Y-shaped configurations.
Product Data
Arrotop is a leading manufacturer, supplier of 2-Valve Manifold Block & Bleed valves, engineered for precision, reliability, and safety in fluid and pressure control applications. These compact manifolds are widely used with static pressure transmitters and gauges, providing effective isolation and safe venting during maintenance or calibration.
Each 2-valve manifold consists of one block valve to isolate the instrument from the process line and one bleed valve to release trapped pressure. Arrotop’s designs conform to international standards, offering long-term durability, leak-free performance, and easy installation in demanding industrial environments.
Ideal for hydraulic systems, instrumentation, and process control, Arrotop’s 2-valve block and bleed manifolds ensure efficient operation and cost-effective maintenance across a range of industries.
