I t d ti t D i C t lIntroduction to Dynamic Controls

Company Background & Overview

C F d d i 1957•Company Founded in 1957

•Prototype Design of Cartridge Valve in 1965

•Cartridge Valves fitted in to UK & US Submarines in the late 1960’s

•UK Patent Obtained in 1972

•In the mid 1980’s the Dutch Frigate program was supplied with pressure

reducing stations utilising the cartridge valve principlereducing stations utilising the cartridge valve principle

•In the early 1990’s Dynamic Controls diversified into other markets,

mainly Petrochemical Oil & Gas and Power Generationmainly Petrochemical, Oil & Gas, and Power Generation

•In the late 1990’s Dynamic Controls acquired BVMI, a manufacturer of

the build process

Can fit specially designed flushing adaptors and blanking

x Noise in Operation

Can fit specially designed flushing adaptors and blanking covers to housings before valve is fitted, reducing inventory complexity and costs

x Noise in Operation

Valves designed to be quiet in operation

Common components used throughout range e.g. 6 different valve body’s can be fitted with 13 different cartridges.

x High Spares / Inventory requirements

y gCommon flushing adaptors and blanking covers.

x High Spares / Inventory Requirements

Our housings form an integral part of the system for life, reducing the need for valve bodies, labour, welding replacements & x-ray labour on replacement welds.

x Servicing and Removal Seat is part of valve and not part of housing.

Cartridge valve fully retractable and all parts including the seat are fully accessible. Retracting open valve to replace the seat is a simple one-touch clip action.Great advantage in an emergency situation where down-time is criticalis critical.
