Product Description

^{The Spring Loaded Double Parallel Sliding Gate Valve offers a cutting-edge alternative to the traditional wedge gate valve, boasting a remarkable reduction in operating torque and drive size. This innovative valve is engineered with a high-performance INCONEL butterfly spring within its internal valve plate, eliminating the need for a conventional coil spring and ensuring effortless integration into the valve body. Its unique compensation structure is designed to prevent jamming, even under high-temperature conditions, effectively countering issues arising from adhesion and wedge extrusion. The valve's plate and seat surfaces are fortified with advanced hardening techniques-such as hard alloy overlay welding and surface spraying of Co-Cr-Ni alloy, WC, or boron-delivering unparalleled self-cleaning capabilities and achieving an impressive surface hardness of HRC90 or higher.

The Spring Loaded Double Parallel Sliding Gate Valve seamlessly pairs with a variety of actuation options, whether pneumatic actuators, electric actuators, electro-hydraulic actuators, or the simplicity of manual actuators, ensuring versatile adaptability to any operational requirement.}

Structural Features

Product Feature

^{Featuring a robust pressure seal bonnet complemented by a high-density pure graphite gasket, ensuring exceptional sealing integrity and durability.}
^{Innovatively designed with an overpressure protection device integrated into the bonnet, this valve is adept at safeguarding against excessive pressure, ensuring optimal safety and performance.}
^{Built with a spring preloaded flat gate valve, this product exhibits superior control and responsiveness in regulating flow.}
^{Engineered with a comparatively wide valve seat and gate, it provides enhanced stability and reliable sealing performance.}
^{Incorporates a precise limit device on the support rod, designed to ensure safe and accurate operation.}
^{Equipped with an anti-rotation device on the valve stem, maintaining alignment and ensuring consistent performance under demanding conditions.}
^{The sealing surfaces are crafted with distinct hardness levels on both ends, preventing excessive wear. Featuring a hardness variation (~5HRC): gate - STLG#, valve seat - STL12#, this design ensures prolonged durability and effective sealing.}
^{Boasting a conical design for the bonnet seal, this configuration guarantees superior sealing efficacy.}
^{Facilitates bidirectional flow, offering versatile application capabilities.}
^{Incorporates two thrust bearings and aluminum bronze sleeves, enhancing the mechanical robustness and operational efficiency.}
^{Designed with an available structure for bypass piping, allowing for increased flexibility in installation and maintenance.}

Spring Compensated Valve Plate Assembly

Features a graphite ring pressure self-sealing structure, offering robust and reliable sealing under varying pressure conditions.

^{Ingeniously crafted to increase the sealing force in response to rising pressure, ensuring a secure and dependable seal.}
^{For applications enduring high temperatures or frequent temperature fluctuations, we recommend opting for graphite pressure sealing gaskets instead of standard soft iron gaskets to guarantee superior performance and resilience in challenging environments.}

Double Parallel Sliding Gate Valves

^{The innovative Double Parallel Sliding Gate Valves replace traditional wedge gate valve structures with a sealing configuration of two parallel gates and a wedging device. This unique separation of the sealing mechanism components ensures excellent sealing even amidst temperature-induced deformation, eliminating issues of jamming due to high temperature expansion.

Upon opening, the valve's sealing disk and seat first disengage and rise via the wedge block effect, significantly reducing friction between sealing surfaces, thus requiring minimal torque, easing operation, and extending service life. This design expertly addresses challenges such as high lifting force demand for single gate operation, sealing surface wear, and poor sealing, while also preventing jamming during high-temperature opening and closing, thereby enhancing sealing performance and longevity.}
