Product Description

^{Delve into the remarkable engineering of the Spring Loaded Double Parallel Sliding Gate Valve, a premium choice for industrial applications. In contrast to the conventional wedge gate valve, this marvel of design boasts a smaller operating torque and more compact drive size. The innovation lies in the internal valve plate, which replaces the traditional coil spring with an advanced INCONEL butterfly spring, ensuring effortless assembly within the valve structure. Its unique compensation structure is crafted to prevent jamming under high temperature conditions, eliminating risks associated with adhesion and wedge extrusion. The surfaces of the valve plate and seat are exceptionally hardened through techniques such as hard alloy overlay welding and surface spraying with Co-Cr-Ni alloy, WC, boron, and more. This results in an astounding self-cleaning capability, with surface hardness reaching HRC90 or even higher.

Experience versatility with the Spring Loaded Double Parallel Sliding Gate Valve, designed for seamless integration with various actuators. Whether you require pneumatic actuators, electric actuators, electro-hydraulic actuators, or manual actuators, this valve provides unmatched compatibility to meet your industrial needs.}

Structural Features

Product Feature

^{Our innovative Spring Loaded Double Parallel Sliding Gate Valves feature a premium pressure seal bonnet, meticulously engineered with a high-density pure graphite gasket, ensuring optimal sealing and uncompromising integrity.}
^{To safeguard against any potential excessive pressure scenarios, an overpressure protection device is thoughtfully integrated into the bonnet, providing reliable security and peace of mind.}
^{Introducing the spring preloaded flat gate valve-designed for precision and robust performance in demanding industrial applications.}
^{With a thoughtfully designed wide valve seat and gate, our product ensures enhanced sealing efficiency and durability.}
^{Equipped with an advanced limit device on the support rod, ensuring operational precision and safety.}
^{The innovative anti-rotation device on the valve stem guarantees stability and prevents unwarranted movement, ensuring consistent performance.}
^{Crafted with differentiated hardness on both ends of the sealing surface, our design minimizes wear and tear. The strategic hardness difference (~5HRC) between the gate - STLG# and valve seat - STL12# ensures long-lasting durability.}
^{Engineered with a conical sealing design on the bonnet, delivering exceptional sealing performance and reliability.}
^{Our valves are designed for bidirectional flow, offering flexibility and adaptability for various system requirements.}
^{Incorporating two thrust bearings and aluminum bronze sleeves, our valves promise reduced friction and enhanced operational efficiency.}
^{Designed with an available structure for bypass piping, our valves offer expanded versatility and system integration options.}

Spring Compensated Valve Plate Assembly

Featuring a graphite ring pressure self-sealing structure, ensuring dependable sealing under varying pressure conditions.

^{Ingeniously designed; as pressure increases, the sealing force correspondingly enhances, providing unparalleled sealing assurance.}
^{For unparalleled performance in high-temperature environments or situations with frequent temperature fluctuations, we strongly recommend utilizing our graphite pressure sealing gaskets. These are superior replacements for standard soft iron gaskets, delivering exceptional reliability and durability for high-temperature and cyclic applications.}

Double Parallel Sliding Gate Valves

^{Revolutionizing traditional valve technology, our Double Parallel Sliding Gate Valves employ an advanced sealing structure with two parallel gates and a wedging device. Unlike conventional wedge gate valves, our design separates the sealing mechanism components, ensuring steadfast sealing capability even under thermal deformation, and eliminating jamming from high-temperature expansion.

Experience effortless operation with our valve design that reduces friction between sealing surfaces during opening. As the sealing disk and valve seat disengage and rise, courtesy of the wedge block effect, operation becomes smooth and torque requirements minimal. This design effectively addresses challenges like high lifting force, sealing surface wear, and high-temperature jamming, significantly boosting sealing performance, operational ease, and extending the valve's service life.}
