1.Features Of Bellows Seal Control Valve
Bellows Seal Control Valve has a compact valve body and an S-shape flow passage that features low pressure loss, allows a large flow capacity, rangeability and high accuracy flow characteristics, complies with the IEC534-2-1976 standards. The Model HLSW Control Valves are widely applicable for reliable control of the most poisonous, flammable, explosive volatile process fluid and rare metal as the bonnet using the bellows seal. And it can be used in a vacuum occasion. The leakage complies with the ANSI B16.104 standards. The actuator integrated with simplest mechanisms utilizes a compact yet powerful diaphragm actuator loaded with multiple springs. This product complies with the GB/T4213-2008 standards.
