Product Description

^{Introducing the Spring Loaded Double Parallel Sliding Gate Valve, a marvel of engineering by SNT Machinery (Qingdao) Co., Ltd. This innovative valve excels over traditional wedge gate valves with its significantly reduced operating torque and compact drive size, offering unparalleled efficiency. At its core, an advanced INCONEL butterfly spring replaces the conventional coil spring, simplifying assembly within the valve body and enhancing durability. The ingenious compensation structure design prevents jamming under high temperature conditions, eliminating adhesion and wedge extrusion issues. Our valve's surfaces are expertly hardened using techniques such as hard alloy overlay welding and surface spraying with Co-Cr-Ni alloy, WC, and boron. This meticulous process ensures a self-cleaning function with an impressive surface hardness reaching HRC90 or above, setting a new standard in performance and reliability.

Versatility at its finest, the Spring Loaded Double Parallel Sliding Gate Valve from SNT Machinery (Qingdao) Co., Ltd. can be seamlessly integrated with a variety of actuators. Choose from pneumatic actuators, electric actuators, electro-hydraulic actuators, or manual actuators to suit your specific operational needs. This adaptability ensures that our valve meets the demands of any application, providing dependable performance and control.}

Structural Features

Product Feature

^{Pressure seal bonnet that boasts a high-density pure graphite gasket, ensuring exceptional sealing capabilities.}
^{An innovative overpressure protection device is integrated into the bonnet, safeguarding the system against excessive pressure for enhanced reliability.}
^{Ingeniously designed with a spring preloaded flat gate valve, ensuring secure and efficient control.}
^{Features a relatively wide valve seat and gate, facilitating robust performance and reliability.}
^{Equipped with a limit device on the support rod for precise operation and enhanced control.}
^{An anti-rotation device on the valve stem ensures stability and prevents unwanted movement.}
^{Designed with differing hardness at both ends of the sealing surface to minimize wear significantly, featuring a hardness difference of approximately 5HRC-gate made of STLG#, valve seat made of STL12#.}
^{Embraces a conical design for bonnet sealing, optimizing sealing efficacy and reliability.}
^{Capable of handling bidirectional flow, offering versatile application and efficiency.}
^{Incorporates two thrust bearings coupled with aluminum bronze sleeves for smooth operation and durability.}
^{Features an available structure for bypass piping, enhancing versatility and system integration.}

Spring Compensated Valve Plate Assembly

Utilizes a graphite ring pressure self-sealing structure for enhanced sealing under varying pressures.

^{Remarkably, the higher the pressure, the greater the sealing force, ensuring uncompromised performance.}
^{In environments characterized by high temperatures or frequent temperature fluctuations, it is advisable to use graphite pressure sealing gaskets as replacements for standard soft iron gaskets, optimizing performance for such demanding conditions.}

Double Parallel Sliding Gate Valves

^{The ingenious Double Parallel Sliding Gate Valves feature a sealing structure with two parallel gates and a wedging device, replacing the conventional wedge gate valve structure. This innovative design keeps sealing components separate, ensuring effective sealing even when subjected to temperature-induced deformations, and avoids jamming due to high-temperature expansion.

Upon opening, the valve's sealing disk and seat disengage and rise, thanks to the wedge block effect, significantly reducing friction between the sealing surfaces. This results in minimal torque requirement, effortless operation, and prolonged service life. This design masterfully tackles challenges such as the significant lifting force needed for single gate initiation, sealing surface wear, poor sealing, reduced service life, and jamming during high-temperature operations, thereby enhancing the valve's sealing performance and longevity.}
