Pressure and Vacuum gauges for general purpose use in Hydraulic or pneumatic applications with standard accuracies. Pressure gauge sizes from 40mm up to 200mm diameter are usually available from stock. For further information ask for our pressure and Temperature catalogue

Pressure and Vacuum Gauges required for special applications, manufactured with Electrical contacts, Diaphragm or non standard process connections for use on hazardous or toxic media, high accuracy, large diameter Analogue or Digital gauges for comparative situations.

Designed specifically for testing reduced pressure zone backflow preventers, incorporating a high accuracy differential gauge to determine effective closure of the check modules. The kit contains a full selection of adaptors, retaining hook and five colour coded hoses. All above contained in a "Photographers" type carrying case.

Reduced pressure backflow prevention assemblies consist of two "Y" pattern check valves and one hydraulically independent differential relief valve, each valve is designed to meet International specifications required for backflow prevention devices. These devices are becoming increasingly popular in supply lines requiring a higher degree of protection.
