Two-way Relief Valve

Description

Two-Way Relief Valve is designed with separate and distinct settings for both vacuum and pressure relief. It can be used for both:

  • Transit and storage containers
  • Electronic and electro-optics equipment

Tamper-proof, these valves have standard settings ranging from 0.5 psid to 3.0 psid reseal pressure. Some of the valves incorporate a desiccant cartridge to allow adsorbing of moisture before entering a piece of equipment or container. These relief valves do not require any field maintenance, and most models feature a manual release push button to equalise pressure or vacuum differentials to open the container or equipment.

Panel Mounting Double Differential Relief Valve

This low-cost, two-way vacuum and pressure relief valve is ideally used for transit cases and similar applications up to 4 cubic feet in volume. Featuring separate and distinct settings for both vacuum and pressure relief, it has a flow rate of 0.5 scfm at a pressure of 1.5 psi to 2.0 psi above value settings. The standard settings range between 0.5 psid to 2.0 psid reseal pressure.

The Panel Mounting Double Differential Relief Valve is incorporated with corrosion-resistant materials throughout the entire tamper-proof breather valve, making field maintenance unnecessary. It also feature valve seals made of silicone rubber, and each valve is supplied with a nut and o-ring for small cases that require a low profile valve. It is also incorporated with a manual release button that is capable of equalising pressure or vacuum differentials to open the container.

0.75 x 16 UNF Double Differential Relief Valve (With Weather Shield)

Featuring a weather shield, this valve is designed to provide a low-cost, two-way vacuum and pressure relief valve that is ideally used for transit cases and similar applications up to 4 cubic feet in volume. It is also incorporated with corrosion-resistant materials throughout the valve, which makes field maintenance unnecessary. Equipped with valve seal made of silicone rubber, each valve is supplied with a nut and o-ring for small cases that require a low profile valve

0.75 x 16 UNF Double Differential Relief Valve (With Weather Shield) consists of separate and distinct settings for both pressure and vacuum relief. It also features a conversion coating housing, which allows the use of a conductive o-ring for minimal RFI shielding. For higher energy RFI Shielding, please contact us for more information.

1.00-20 UNEF Thread Double Differential Relief Valve

This breather valve is best suited for transit cases or other similar applications up to 33 cubic feet in volume. This breather valve is designed to be low cost, but with a higher flow valve of 4.0 scfm in comparison with the Paul Mounting Double Differential Relief Valve.

Lightweight, rugged, tamper-proof, it does not require any field maintenance as corrosion-resistant materials are used throughout as well as a silicon rubber seal. Just like other breather valves, it features a manual release button which is used to equalise residual pressure or vacuum differentials to open the container.
The valve is also available in settings ranging between 0.5 psi to 5.0 psi.

3/4 “ Thread Double Differential Relief Valve

Consist of separate and distinct settings for both vacuum and pressure relief, this breather valve comes with a flow rate that ranges between 1.5 to 4.0 scfm at 1.5 psi above the reseal setting. Ideal for containers and similar applications up to 33 cubic feet in volume, it features standard settings available from 0.25 psid to 3.0 psid reseal pressure. The lower the setting, the higher the flow rate.

Made with corrosion-resistant material throughout and silicone rubber for the valve seal, however, the spherical valve seat is Teflon coated for easy “break-away” action even after prolonged storage. This Breather Valve is tamper-proof and does not require any field maintenance.

This breather valve also comes with a manual release push button, used to equalise the pressure or vacuum differentials to enable the easy opening of the container. The button is recessed in the cover to protect it from damages and eliminate the possibility that an adjacent container might press the button on accident, causing the valve to remain open. The button is equipped with a unique feature, a light-duty spring, under the cover which separates it from the vacuum stem, that must be overcome before the button opens the valve.

The valves are also available in two types: “Cracking” and “Reseal”.

Cracking Valves are rated by cracking pressure and the flow rate at 1.5 psi above the cracking pressure, while Reseal Valves are rated by the reseal pressure and the flow rate at 1.5 psi above the reseal pressure. Gasket, washer and hex nut are provided with each valve. The weldable nut is available for use as a threaded boss, or the valve may be used with our mounting Flanges. RFI/ EMI shielding is also available.

  • *Cracking pressure: Pressure at which the valve has opened enough to flow 1 cubic centimetre per minute.
  • *Reseal pressure: Pressure at which the valve is guaranteed to close after it has cracked open.

2.00-18 UNS Thread Double Differential Relief Valve

Consisting of a separate and distinct setting for both pressure and vacuum relief, the Thread Double Differential Relief Valve features a flow rate of 10.0 to 25.0 psi above the valve setting, and a standard-setting range from 0.5 psid to 5.0 psid reseal pressure. This makes it ideal for applications such as large containers and similar applications up to 206 cubic feet in volume.

This breather valve also comes with a manual release push button, used to equalise the pressure or vacuum differentials to enable the easy opening of the container. The button is recessed in the cover to protect it from damages and eliminate the possibility that an adjacent container might press the button on accident, causing the valve to remain open. The button is equipped with a unique feature, a light-duty spring, under the cover which separates it from the vacuum stem, that must be overcome before the button opens the valve.

The valves are also available in two types: “Cracking” and “Reseal”.

Cracking Valves are rated by cracking pressure and the flow rate at 1.5 psi above the cracking pressure, while Reseal Valves are rated by the reseal pressure and the flow rate at 1.5 psi above the reseal pressure. Gasket, washer and hex nut are provided with each valve. The weldable nut is available for use as a threaded boss, or the valve may be used with our mounting Flanges. RFI/ EMI shielding is also available.

The Thread Double Differential Relief Valve is covered with corrosion-resistant material throughout with a silicone rubber valve seal. In addition, it also has a spherical valve seat that is coated with Teflon for easy “break-away” action even after prolonged storage. It is also tamper-proof and does not require any field maintenance.
