The Two-Way Relief Valves can be used for transit and storage containers, and electronic and electro-optics equipment. The tamper-proof valves have standard settings ranging from 0.5 psid to 3.0 psid reseal the pressure. These do not require any field maintenance. The valves have a manual release push-button for equalising the pressure or vacuum differentials to open the container or equipment.
The Two-Way Relief Valves are available in different models:
This low-cost, two-way vacuum and pressure relief valve is ideal 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 features 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 capable of equalising pressure or vacuum differentials to open the container.
Featuring a weather shield, this valve is designed to provide a low-cost, two-way vacuum and pressure relief valve that is ideal 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 a 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. The 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.
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 than the Paul Mounting Double Differential Relief Valve. Lightweight, rugged, tamper-proof, the 1.00-20 UNEF Thread Double Differential Relief Valve does not require any field maintenance as corrosion-resistant materials are used throughout as well as a silicon rubber seal. Like other breather valves, it features a manual release button 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.
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, which 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.
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 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, which 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. It also has a spherical valve seat coated with Teflon for easy “break-away” action even after prolonged storage. It is also tamper-proof and does not require any field maintenance.
Made from Anodised Aluminium, the M14 Thread Double Differential Relief Valve can protect enclosures from the imbalance of internal and external pressure. The weather shield provides additional protection and can be supplied with R.F. Screening Continuity when required. The valve is also available in a wide range of pressure settings.
Stainless Steel Relief Valve is a two-way pressure relief valve that can be used together with a desiccator with the help of the M20 Internal Thread on the rear. The valve features a key slot on the front and a Diamond Kurl cut body to enable easy fitting. The valve is available in a wide range of pressure settings.
Designed to protect enclosures from the imbalance between internal and external pressure, this valve is made from a mixture of stainless steel and polycarbonate. It requires a 30.5mm diameter hole and is fitted with a manual override button to ensure safe equipment opening. The valve is available in a wide range of pressure settings.
Two Way Relief Valve is FDA approved, enabling usage in medical and food devices such as releasing the steam build up in cookers or equalise pressure in medical storage containers.
Made from Anodised Aluminium, the Two Way Pressure Relief Valve can protect enclosures from the imbalance of internal and external pressure. It has a square drive which allows it to be torque at 60 lb/in.
Made from Anodised Aluminium, the ½” 20 UNF Thread can protect enclosures from the imbalance of internal and external pressure. The valve also has a weather shield for added protection and can be supplied with R.F. Screening Continuity when required.
The Thread: ½” 20 UNF is specially designed for both electronic and electro-optic equipment and transit and storage containers. This valve is tamper-proof and does not require any maintenance. A 0.5 psid – 3.0 psid reseal pressure can be incorporated with a highly absorbent desiccant to remove moisture from the air that enters the container or storage. It is also easy to use and install.
