- Rotary Switch:Similar to Rotary Valves in construction, they have a common outlet and four inlet ports or vice versa. The Switch provides selection of connecting any one inlet with one outlet per position
- Key Operated Valve: Essentially a spool type DCV this valve can be operated only by a special key provided with the valve. These valves are made mainly for applications where unauthorized or erroneous control is to be prevented.
- Automatic Signal Lock Up Relay: these are relays which automatically lock-up the transmitted signal whcn the supply pressure falls. They are mainly used with Diaphram control valves to maintain position when supply pressure fails.
We have developed many valves for special applications. Some of the most common valves are listed below:
