Product Description

^{The state-of-the-art Efficient Spring Loaded Double Parallel Sliding Gate Valve for Gas Medium is engineered to outperform traditional wedge gate valves with its reduced operating torque and compact drive size. Ingeniously crafted, the internal valve plate incorporates an advanced INCONEL butterfly spring, replacing conventional coil springs for seamless integration within the valve body. Moreover, its innovative compensation structure design prevents jamming due to high temperatures caused by adhesion and wedge extrusion. The valve plate and seat surfaces are fortified with superior hardening processes, including hard alloy overlay welding and surface spraying with Co-Cr-Ni alloy, WC, and boron, ensuring exceptional durability and a self-cleaning capability with an impressive surface hardness reaching HRC90 or higher.

The versatile Efficient Spring Loaded Double Parallel Sliding Gate Valve is designed to seamlessly integrate with a range of actuators, including pneumatic, electric, electro-hydraulic, or manual actuators, offering unparalleled adaptability to meet your specific operational needs.}

Structural Features

Product Feature

^{Experience ultimate sealing efficiency with our pressure seal bonnet, expertly crafted using a high-density pure graphite gasket; your guarantee for enduring resilience.}
^{Introducing an advanced overpressure protection device within the bonnet, ensuring robust defense against excessive pressure, safeguarding your operations seamlessly.}
^{Our gate valve boasts a sophisticated spring preloaded flat design, delivering exceptional performance and reliability.}
^{With a wide valve seat and gate, our product ensures enhanced stability and consistent performance for your gas medium workflows.}

^{Featuring an innovative anti-rotation device on the valve stem, this design ensures steadfast alignment and superior functionality.}
^{Crafted with precision, the sealing surface features different hardness levels on each end to minimize wear significantly. With a strategic hardness difference (~5HRC): gate - STLG#, valve seat - STL12#, it promises extended durability.}
^{Our bonnet sealing is designed with a conical shape, providing impeccable sealing integrity and reliability.}
^{Facilitating bidirectional flow, this valve offers versatile applications across diverse operational scenarios.}
^{Integrating two thrust bearings and aluminum bronze sleeves, our design ensures smooth operation and heightened durability.}
^{Engineered with an available structure for bypass piping, our product supports enhanced operational flexibility.}

Spring Compensated Valve Plate Assembly

Utilizing an advanced graphite ring pressure self-sealing structure, this mechanism guarantees superior sealing under varying pressures.

^{Ingeniously designed, the sealing force amplifies with pressure increases, ensuring steadfast and reliable operation across variable conditions.}
^{In environments subject to high temperatures or frequent temperature fluctuations, we strongly recommend utilizing graphite pressure sealing gaskets as replacements for standard soft iron gaskets. These are ideal for high-temperature and frequent temperature cycle applications, providing enhanced resilience and safety.}

Double Parallel Sliding Gate Valves

^{Our cutting-edge Double Parallel Sliding Gate Valves innovatively replace the traditional wedge gate valve structure with a sealing system comprising two parallel gates and a wedging device. Its unique design ensures reliable sealing even under thermal deformation, preventing jamming caused by high temperature expansion.

When the valve opens, the sealing disk and valve seat initially disengage, then rise via a wedge block effect, dramatically reducing friction between sealing surfaces. This results in minimal torque, effortless operation, and extended service life. Our design successfully addresses challenges such as high lifting force for single gate start, sealing surface wear, poor sealing, short lifespan, and jamming during high-temperature operations, thereby enhancing both the sealing performance and longevity of the valve.}
