Also known as block and bleed valves, these have two vent ports to isolate pressure gauges, switches, and other components in high-pressure systems for maintenance, calibration, and sampling without interrupting the process. They are rated for up to 10,000 psi. Use with water, oil, air, and inert gas. Turn the handle to adjust flow in small increments for metering, sampling, and other applications requiring fine flow control.

Also known as block and bleed valves, these have a vent port that allows you to remove instrumentation equipment attached to the valve without depressurizing your line. Turn the handle to shut off flow and remove the vent port plug to drain liquid trapped in the valve. Use them with water, oil, air, and inert gas. These valves adjust flow in small increments for metering, sampling, and other applications requiring fine flow control.
