V6000 Series Three-way Control Valve

Description

In the heating field, the three-way control valve is a common fluid control component that can replace two two-way control valves to regulate temperature and flow rate. These valves can be categorized as either combination flow and diversion type according to their functionality. Common issues with three-way control valves include difficulty in disassembling and replacing valve seats, packing wear and leakage, poor adjustment accuracy, stem breakage or detachment, and large leakage,which cannot meet operational requirements, lead to emergency in severe cases shutdowns, resulting in substantial losses for users.

Regarding above potential hazards, the Newton R&D team conducted in-depth users’ sites and extensive information gathering regarding operational conditions, as well as technological breakthroughs and through extensive validated tests and experiments making the designs, manufacturing, and batch deliveries of the V6000 series three-way control valves fully meet users’ requirements.

Structure and Characteristics

1. Three-way control valve

① Valve stem double-guided structure
Keeping the packing and valve stem coaxial at all times can prevent abnormal wear of the packing caused by eccentricity,greatly improving the service life of the packing.

② Up-pressure valve seat structure
By loosening the valve cover bolts, the internal components of the valve can be removed one by one, allowing for quick maintenance and replacement of the valve seats and internal components on-site, thus saving the user’s maintenance time

③ Sealing Gasket Quantitative Compression Structure
Prevent the gasket from being overly compressed to achieve durable sealing without leakage.

④ Single seat sealing structure
Lower leakage and hard seling can meet level V and above leakage requirements for a long time

⑤ Valve plug double-guided structure
The valve plug operates smoothly, not prone to vibration and sticking, ensuring higher regulating precision.

⑥ Spring-loaded packing gland structure
Provide a continuous and stable compressive force for the packing, allowing the
packing to automatically compensate for wear during use, achieving long-term stable sealing.

2. Three-way bellows control valve

① Bellows external pressure-bearing structure
Provides a stable pressure load for the bellows, reducing movement and improving both the bellows’lifespan and the valves’ operational precision. Compared to an internal pressure-bearing structure, an external.pressure-bearing structure increases the maximum allowable stress on the bellows, thereby enhancing its service life.

② Bellows and flow channel separation structure
Prevents the medium from directly impacting the bellows, thereby increasing the service life of the bellows.
