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.

Swagelok purge valves are manual bleed, vent, or drain valves. The knurled cap is permanently assembled to the valve body for safety. One-quarter turn with a wrench from finger-tight obtains leak-tight closure on first makeup. Snugging with a wrench ensures closure to the rated pressure with subsequent makeups. Wetted components listed in italics.

Bleed valves, purge valves, and relief valves are all pressure-control valves, but they each have a special purpose. Let’s find out what the difference is for these products and how to choose the one you need. What is a Bleed Valve? A bleed valve is a valve that typically utilizes a threaded bleed screw to open or close.

Parker BV Series Bleed Valves are designed for use on products such as multi-valve manifolds or gauge/root valves. Functionally, the valve vents line pressure either to atmosphere or to containment when used with the optional

Hy-Lok purge valves are designed to manually bleed, vent or drain. Hy-Lok USA, Inc. bleed valves can be used on instrument fluid handling products, such as manifolds or gauge/root valves, in order to vent signal line pressure to the atmosphere before disassembling of an instrument or to facilitate in the calibration of control devices.

2021年5月26日 · A bleed valve is a simple fluid handling device used to relieve pressure, vent fluid or bleed air from a closed system. These functions are generally necessary before any maintenance or repair work can be conducted on a pressurized fluid line. The design of a bleed valve resembles a pipe plug with a screw threaded in from the top.

2025年1月21日 · Bleed valves are critical in pressure vessels to vent excess gases or air and prevent dangerous pressure buildup. Types of Bleed Valves. There are different types of bleed valves, each suited for specific applications: Manual Bleed Valves: These require manual operation to open and close the valve. They are typically used in systems where the ...

Superlok bleed valves, also known as vent valves or drain valves, are essential components in fluid control systems designed to relieve pressure, remove trapped air or gas, and simplify maintenance tasks.

Bleed valves from Pneumadyne are available in 10-32 UNF, 1/4 NPT and 1/8 NPT thread sizes and are electroless nickel plated for corrosion resistance. Bleeder valves automatically release excess pressure in a system and are used for various plumbing applications. Request a quote for bleed valves today.
