Product Description

^{Discover the unparalleled excellence of our spring loaded double parallel sliding gate valve. Engineered with precision, it offers a substantial advantage over traditional wedge gate valves by delivering a significantly reduced operating torque and a more compact drive size. The innovative internal design features an INCONEL butterfly spring, replacing the conventional coil spring, ensuring seamless assembly within the valve body. Its unique compensation structure design effectively prevents jamming, even under high-temperature conditions, eliminating issues from adhesion and wedge extrusion. Engineered for longevity and superior performance, the valve plate and seat surfaces are fortified with a hard alloy overlay welding and surface spraying of Co-Cr-Ni alloy, WC, or boron compounds, achieving a remarkable surface hardness of HRC90 or higher. This advanced hardening provides not only durability but also an exceptional self-cleaning function, ensuring reliability in demanding environments.

Versatility meets efficiency with our spring-loaded double parallel sliding gate valve. It offers seamless compatibility with a range of actuator options, including pneumatic actuators, electric actuators, electro-hydraulic actuators, and manual actuators, providing unparalleled flexibility to suit your operational needs.}

Structural Features

Product Feature

^{The pressure seal bonnet boasts an advanced high-density pure graphite gasket, ensuring superior sealing and reliability.}
^{An innovative overpressure protection device is integrated into the bonnet to guard against excessive pressure, enhancing safety and durability.}
^{Features a spring preloaded flat gate valve, combining precision engineering with robust performance.}
^{Designed with a relatively wide valve seat and gate, offering enhanced stability and sealing efficiency.}
^{Equipped with a limit device on the support rod for precise control and operational safety.}
^{Incorporates an anti-rotation device on the valve stem, ensuring consistent performance and durability.}
^{Features differentiated hardness on both ends of the sealing surface to prevent wear; a hardness difference of approximately 5HRC: gate - STLG#, valve seat - STL12#, ensuring longevity and reliability.}
^{Utilizes a conical design for bonnet sealing, guaranteeing a tight and secure fit.}
^{Supports bidirectional flow to enhance flexibility and adaptability in various applications.}
^{Incorporates two thrust bearings and aluminum bronze sleeves, offering smooth operation and added durability.}
^{Provides a sophisticated structure for bypass piping, optimizing flow management.}

Spring Compensated Valve Plate Assembly

Employs a graphite ring pressure self-sealing structure, ensuring robust and reliable sealing under pressure.

^{Ingeniously designed to increase sealing force with rising pressure, maximizing sealing integrity.}
^{In high-temperature or rapidly fluctuating temperature conditions, we highly recommend utilizing graphite pressure sealing gaskets as a superior alternative to standard soft iron gaskets, perfect for high-temperature and frequent temperature cycling applications.}

Double Parallel Sliding Gate Valves

^{The Double Parallel Sliding Gate Valves feature an innovative sealing structure with two parallel gates and a wedging device, replacing the conventional wedge gate valve structure. This innovative mechanism ensures continuous sealing even under temperature-induced deformations, preventing jamming caused by thermal expansion.

Upon opening, the valve's sealing disk and seat disengage before rising due to the wedge block effect, significantly reducing friction on sealing surfaces. This results in minimal torque requirements for easy operation and an extended service life. This design effectively resolves issues such as the significant lifting force needed for single gate initiation, wear on sealing surfaces, suboptimal sealing, brief service life, and high-temperature jamming, thereby enhancing both the valve's sealing proficiency and longevity.}
