Air Start Valves

Economical in price and maintenance
Seetru can apply the latest large-scale manufacturing technologies to ensure economic first costs. Economy in use is ensured by the ease of installation and simple maintenance procedure.

Safety valve connection
A threaded connection is provided on the manifold unit for a safety valve to protect the air receiver. Safety valves can be supplied as optional extras, contact Seetru for information on our range of safety valves. (An enclosed discharge valve may be preferred where equipment is protected by a fire control system.)

Shut-off valve connection for pressure gauge
A connection with a shut-off valve is provided on the manifold unit for a pressure gauge, which can be fitted to monitor the pressure in the air receiver. Pressure gauges can be supplied as optional extras, contact us for information.

Integrated inspectors test point
A connection is provided for the connection of an inspector’s pressure test gauge.

Fusible plug thermal protection
The GS56 has the facility for a fusible thermal plug to protect the air receiver from over-pressure due to heat (e.g. In the case of fire). The plug fuses at a defined temperature and releases the pressurized air in the receiver. Plugs are supplied as optional extras.

Siphon drain valve
An optional siphon drain valve can be supplied with the GS56. This valve is connected to a long tube, which reaches low into the receiver vessel when opened, the pressure in the vessel forces any oil or water out through the tube.

Widely accepted worldwide approvals
Accepted by Lloyds for marine applications. Testing can be witnessed by marine approval authorities prior to despatch and certification is provided at extra cost. Compliant with the requirements of the European Pressure Equipment Directive, PED (CE marked).
