In the fields of heating, temperature control, refrigeration, and even the entire field of industrial fluid automation, GlOBE straight-Travel control valve is a common and indispensable fluid control component. The control valve achieves the regulation of steam and other fluids’ pressure, flow rate, temperature and fluid level, which mainly through changing the throttling area between the valve plug and valve seat. Common issues with regular GLOBE straight-Travel control valves include difficulty in disassembling and replacing valve seats, packing wear and leakage, poor regulating accuracy, weak sealing, especially in high temperature conditions where it is prone to stick, excessive vibration and noise, stem breakage or detachment, and large leakage, which cannot meet operational requirements, lead to emergency shutdowns in severe cases, resulting in substantial losses for users.
The V8000 model solves the above problems well and owns the following features:
Keeping the packing and valve stem coaxial at any
times can prevent abnormal wear of the packing
caused by eccentricity,greatly improving the service life of the packing.
The valve plug and the valve stem is tightly connected by threads and pins, with no any relave movement
gap, effectively prevent fatigue and fracture of the
valve stem from relative swing of the valve plug and
valve stem.
By loosening the valve bonnet bolts, the internal components of the valve can be removed one by one, allowing for quick maintenance and components on-site, thus saving the user’s replacement of the valve seat and internal maintenance me
Prevent the gasket from being overly compressed to achieve durable sealing without external leakage.
Lower leakage and hard sealing can meetlevel V and above leakage requirements for a long time.
Under high-temperature conditions, the pressure cage can absorb the axial displacement caused by high temperatures and convert it into radial elastic deformation, prevent the gasket or valve internal components from failing due to thermal stress deformation.
The valve plug operates smoothly, not prone to vibriaon and scking, ensuring higher regulang precision.
Provide a connuous and stable compressive force for the packing, allowing the packing to automacally compensate for wear during use, achieving long-term stable sealing.
Balanced single-seat control valve
The wear-resistant piston ring sll has self-lubricang at temperatures above 200°C, making the valve not easy to stretch and block during the long period regulang process, maintaining a seal grade above level IV .
Low thrust overcomes the large pressure difference, has beer performance of overcoming differenal pressure.
The throling orifice is uniformly distributed on the valve plug, allowing the medium to flow smoothly and stably, thus achieving higher regulang precision.
Low noise control valve
Low noise valve plug structure
This design reduces the flow speed of the medium, thus diminishing the erosion of the valve plug and seat caused by high flow speed, increasing its service life.It also lowers noise, reducing environmental noise polluon.
Decreased vibraons, prevent damage to valve internal components from high-frequency vibraons, enhancing regulang precision and service life.
Multi-stage pressure reducing control valve
Multi-stage pressure +reducing valve plug structure
Used in conditions with high differential pressure to reduce medium flow speed and minimize the erosion to the valve plug and seat that occursat high speed, thereby prolonging the valve’s service life.It also reduces noise, lessening noise pollution to the environment The structure also diminishes vibraons, preventing damageto valve internal components due to high-frequency vibrations and improving the precision of regulation as well as service life.
Pilot control Valve
Pilot operated valve plug structure
Equipped with regulating and shut-off function, it has excellent sealing performance under high temperature (>230 ℃) working conditions and can ensure long-term operation with sealing above level V.The structure also diminishes vibrations, prevenng damageto valve components due to high-frequency vibrations and improving the precision of regulation as well as service life.
