wall mount stop valve bathroom basin faucets The VQS is a steam turbine quick stop valve with a proven design and technology for protection of steam turbines.
The VQS has a fast and reliable quick stop function for protection of the steam turbine if it is tripped.
This is achieved with a mechanical spring that is used for the emergency shutoff.
The closing time is typically less than 0.2s for full stroke, though a shorter closing time is available.
As a safety feature the valve has a built-in test facility in order to test the quick stop function during turbine operation.
This online exercise capability demonstrates tripping components' freedom of movement without affecting steam flow.
This emergency quick close function achieves maximum protection for the turbine.
The lifetime of the turbine blades is extended with a built-in strainer that provides protection for the turbine.
As an integrated part of the bonnet, this built-in strainer protects the tightening surfaces and the downstream equipment from dirt and particles larger than 0.8mm.
The VQS increases power production by allowing a low pressure drop over the valve.
The low total pressure drop over the valve improves the energy efficiency of the installation, thus improving power production.
The VQS's customised design fits most turbine manufacturers' equipment.
This well-proven design and technology also has high reliability, with each valve independently calculated and designed according to the relevant operational conditions.
The valve body, of fully machined forged CrMo alloy or carbon steel, is designed to minimise material stresses as well to fit the requirements of piping system with regard to material, pressure rating and piping connections.Fore more information ,please visit http://www.bossgoo.com/
