Product Description

Product Description

<sup>The Spring Loaded Double Parallel Sliding Gate Valve from SNT Machinery (Qingdao) Co., Ltd. is engineered for unrivaled efficiency and high performance in fiber transport. Compared to the traditional wedge gate valve, this innovative valve boasts a significantly reduced operating torque and a more compact drive size, ensuring smooth and seamless operation. At its core, the valve features an INCONEL butterfly spring instead of a conventional coil spring, simplifying the assembly process within the valve body for enhanced reliability. With its advanced compensation structure design, this valve adeptly prevents jamming caused by high temperatures, adhesion, and wedge extrusion, maintaining optimal functionality even under challenging conditions. The valve plate and seat surfaces are fortified through hard alloy overlay welding, surface spraying with Co-Cr-Ni alloy, WC, and boron, offering a self-cleaning mechanism and achieving extraordinary surface hardness of HRC90 or higher. This superior construction ensures durability and longevity, making it a standout choice for demanding industrial applications.

Versatility meets innovation with the Spring Loaded Double Parallel Sliding Gate Valve, as it seamlessly integrates with a variety of actuator options. Choose from pneumatic actuators for fluid-driven precision, electric actuators for efficient energy use, electro-hydraulic actuators for advanced control, or manual actuators for traditional hands-on operation. This flexibility ensures that the valve can be customized to meet the specific needs of any application, providing tailored solutions and maximizing system efficiency.</sup>

Structural Features

 

Product Feature

 

^{Experience exceptional sealing performance with our pressure seal bonnet, enhanced with a high-density pure graphite gasket, ensuring optimal protection and reliability.
Innovatively designed with an overpressure protection device within the bonnet, safeguarding against excessive pressure and enhancing operational safety.
Engineered with a robust spring preloaded flat gate valve for superior control and performance in demanding environments.
Featuring a relatively wide valve seat and gate, this design ensures long-lasting durability and consistent functionality.
Equipped with a precision limit device on the support rod, delivering enhanced stability and operational accuracy.
Incorporates an anti-rotation device on the valve stem, ensuring precise alignment and reduced wear over time.
Designed with distinctive hardness on sealing surfaces, preventing significant wear. The gate employs STLG# while the valve seat uses STL12#, with a hardness difference of approximately 5HRC.
The bonnet features a conical sealing design, offering superior sealing integrity and performance.
Facilitates bidirectional flow, enhancing versatility and adaptability for a wide range of applications.
Incorporates two thrust bearings with aluminum bronze sleeves, providing smooth operation and increased longevity.
Includes an available structure for bypass piping, adding flexibility and customization to meet specific system requirements.}

Spring Compensated Valve Plate Assembly

Integrates a graphite ring pressure self-sealing structure, automatically adjusting to pressure variations for optimal sealing efficiency.

^{Ingeniously designed: the higher the pressure, the stronger the sealing force, ensuring unwavering reliability even under intense conditions.
For high-temperature or frequently changing temperature conditions, we recommend graphite pressure sealing gaskets over standard soft iron. Ideal for high-temperature and frequent temperature cycle applications, they enhance durability and performance.}

Double Parallel Sliding Gate Valves

<sup>Our Double Parallel Sliding Gate Valves use an advanced sealing structure with two parallel gates and a wedging device, replacing traditional wedge gate valves. This design features separate sealing components, ensuring consistent performance under temperature-induced deformation without jamming from thermal expansion.

Upon opening, the valve's sealing disk and seat disengage and rise due to the wedge block effect, minimizing friction. This results in reduced torque, ease of operation, and extended service life. The innovative design overcomes common challenges like high lifting force, sealing surface wear, poor sealing, short service life, and high-temperature jamming, thereby enhancing the valve's sealing performance and longevity.</sup>
