Block and Bleed Needle Valves by FlowBiz – Precision Instrumentation & Pressure Calibration Isolation

Accurate pressure measurement, instrument isolation, and safe calibration routines require robust control components that can safely isolate and vent high-pressure process media. FlowBiz Block and Bleed Needle Valves integrate process isolation (block valve) and pressure venting (bleed valve) into a single compact barstock body, reducing leak paths and enhancing site safety.

Engineered with high-tensile stainless steel (SS304 / SS316) barstock construction rated up to 6000 PSI (413 Bar), this 2-valve manifold configuration simplifies instrument mounting, in-situ gauge calibration, and pressure transmitter venting. FlowBiz block and bleed valves feature color-coded dust caps, non-rotating needle tips, and high-integrity PTFE/Graphite stem packings for precise throttling and leak-tight shut-off.

Key Applications Across Process & Instrumentation Control

FlowBiz Block and Bleed Needle Valves offer critical isolation and venting functions across process utilities:

• Pressure Gauge & Transmitter Mounting: Provides complete process line isolation and instrument venting during routine maintenance or replacement.
• In-Situ Calibration: Allows technicians to vent trapped pressure between the block valve and gauge to connect external calibration equipment.
• Chemical & Petrochemical Lines: Safely isolates hazardous liquids and gases from monitoring equipment.
• High-Pressure Hydraulic & Gas Manifolds: Prevents pressure spikes and ensures safe sampling in oil, gas, and power plants.
