1 What is a bellows gate valve?

A bellows gate valve is a special gate valve that is improved by adding one or more sets of bellows to form a double-sealed gate valve. The bellows acts as an expansion joint, allowing the valve to bend and stretch to compensate for movement in the piping system. This helps prevent pressure-related damage and ensures optimal performance.

2 What are the advantages of bellows gate valve produced by Freeman Valve?

2.1 The bellows-sealed gate valve design eliminates the shortcomings of ordinary valve gate valve stem packing seals that age quickly and are prone to leakage. It improves energy efficiency, increases the safety of production equipment, reduces maintenance costs and frequency, and provides better cleanliness and safety, making these valves useful in many industrial working environments;

2.2 The bellows gate valve is a double-sealed design consisting of bellows and packing, with reliable sealing effect and excellent leak-proof performance, that is, zero leakage, which is very suitable for high-risk media such as toxic and harmful;

2.3 The bellows gate valve can achieve zero liquid loss. The leak-free performance of the bellows gate valve results in no fluid loss, which reduces energy consumption, promotes environmental friendliness, and improves plant equipment safety for employees;

2.4 Bellows gate valve are more durable than ordinary gate valve. The bellows gate valve sealing surface is welded with hard alloy, which is wear-resistant and corrosion-resistant;

2.5 The opening and closing stroke of the bellows sealed gate valve stem is relatively short, so it is very suitable for regulating or cutting off flow, as well as throttling. Since the change in the valve seat opening is proportional to the stroke of the valve disc, this valve is an ideal choice for flow regulation;

2.6 The bellows seal design of the bellows sealed gate valve does not require maintenance, which can reduce operating costs.
