Bailey 480 Cartridge Assembly Relief Valve

This spring operated liquid relief valve has a cartridge type assembly which can be withdrawn from the body without disturbing the spring setting and hence relieving pressure. This allows the seating surfaces to be cleaned without the need to reset the valve. Typically for use on positive displacement pumps, for relief or bypass duties. The spring cartridge assembly can be supplied separately for use as an integral pump bypass relief valve. The spindle is fitted with an ‘O’ ring to protect the spring particularly on corrosive duties.

Aluminium Bronze Ball Valves from several leading manufacturers. Please contact us with your requirements.

Budenberg 269 BFMIRA Vacuum Gauge

The Budenberg 269 BFMIRA Patent Can Piercing Vacuum Gauge is a high specification vacuum gauge specifically designed for the estimation of the intensity of vacuum in a food can. Using an ordinary vacuum gauge fitted with a piercer is usually very inaccurate and does not allow for the dilution of the head space vacuum by entry of air at atmospheric pressure from the gauge. Ordinary vacuum gauges therefore always give a lower reading than the vacuum which existed in the head space before the can was pierced, and if the head space is small the error is compounded. This gauge was developed by the British Food Manufacturing Industries Research Association and it overcomes the disabilities in an ingenious manner. A circular calculator can be provided with the instrument to carry out the calculations in units of ins Hg, cm Hg and Kpa. We have an interesting article relating to Pressure Gauge Selection in the Technical section on this website.

Rupture Disc Accessories

Excess flow valves have been designed to prevent pressure accumulation in the space between the rupture disk discharge and the second safety device. Since rupture discs are differential pressure devices, avoiding pressure accumulation is essential to ensure correct disc opening at the desired bursting point. Excess flow valves are usually used when rupture discs are used together with a safety valve or when installed on multiple rupture discs in series. Excess flow valves close when exposed to the rupture disc discharge flow. Excess flow valves are available in ¼” or ½” versions and can be supplied with T connectors, nipples and pressure gauges upon request. All Rupture Discs accessories are made of stainless steel.

Rhodes 400 Sight Glass with Spinner - UK Manufactured

A low cost, ‘entry level’ sight flow indicator with either a high sensitivity spinner operating from 0.7 l/m (water). The nitrile seals and nylon spinner give excellent chemical resistance which is further enhanced in the stainless steel version by the use of borosilicate glass as standard. These compact sight flow indicators are used extensively in plant protection applications to show coolant or lubrication flow to pumps, compressors, and engines. As an added advantage the series 400’s can be used in any orientation.
Rhodes Sight Glasses are fully UK manufactured with castings from the UK, unlike many of the competitors using components from the far east.

Bailey Birkett G4 Pressure Reducing Valve

The G4 piloted operated pressure reducing valve provides extremely accurate levels of pressure regulation for steam, air, and industrial gas applications. The highly sensitive pilot valve provides a constant outlet pressure, irrespective of erratic inlet pressure or system demand.
