Product Description

^{Dive into the world of innovation with our Advanced Spring Loaded Double Parallel Sliding Gate Valves with Pneumatic Actuation! Compared to traditional wedge gate valves, our cutting-edge design boasts an impressively reduced operating torque and compact drive size. At the heart of this engineering marvel lies an INCONEL butterfly spring, replacing the conventional coil spring, which streamlines assembly within the valve body. Our especially crafted compensation structure ingeniously prevents jamming, even under high-temperature conditions, effectively mitigating issues from adhesion and wedge extrusion. The valve plate and seat surfaces are fortified with hardening techniques such as hard alloy overlay welding, and surface spraying with Co-Cr-Ni alloy, WC, boron, etc., ensuring a self-cleaning functionality with surface hardness reaching an extraordinary HRC90 or above, promising longevity and peak performance.

The versatility of our spring loaded double parallel sliding gate valves shines through as they seamlessly integrate with pneumatic actuators, electric actuators, electro-hydraulic actuators, or manual actuators, offering unmatched adaptability to meet diverse operational needs.}

Structural Features

Product Feature

^{Our sophisticated pressure seal bonnet is harmoniously crafted with a high-density pure graphite gasket, ensuring unparalleled sealing efficiency and durability.}
^{An innovative overpressure protection device is ingeniously incorporated into the bonnet, safeguarding the system from excessive pressure and ensuring reliable performance under varying conditions.}
^{Cutting-edge spring preloaded flat gate valve designed for optimal functionality and efficiency.}
^{Features a robust, relatively wide valve seat and gate, enhancing operational stability and sealing effectiveness.}
^{A meticulously engineered limit device on the support rod guarantees precision in motion control.}
^{A sophisticated anti-rotation device on the valve stem for stability and precise alignment.}
^{The sealing surface is ingeniously designed with different hardness levels on both ends, preventing significant wear. With a strategic hardness difference (~5HRC): gate - STLG#, valve seat - STL12#, it ensures longevity and reliability.}
^{Our bonnet sealing features a masterfully designed conical shape, optimizing sealing efficiency.}
^{Allows seamless bidirectional flow, offering versatility and enhanced performance in diverse applications.}
^{Equipped with two thrust bearings and aluminum bronze sleeves, delivering smooth operation and extended service life.}
^{Flexibility in design with an available structure for bypass piping, catering to varied system requirements.}

Ingenious Spring Compensated Valve Plate Assembly for superior sealing and functionality.

Employs a graphite ring pressure self-sealing structure, ensuring high efficiency and reliability under dynamic pressures.

^{Ingenious design feature: the higher the pressure, the greater the sealing force, ensuring airtight performance under intense conditions.}
^{For high-temperature or frequently changing temperature conditions, we highly recommend our advanced graphite pressure sealing gaskets. These are ideal replacements for standard soft iron gaskets, especially in high-temperature and frequent temperature cycle applications, ensuring superior performance and reliability.}

State-of-the-Art Double Parallel Sliding Gate Valves

^{Our Double Parallel Sliding Gate Valves revolutionize conventional designs with a sealing structure of two parallel gates and a wedging device. This innovative configuration replaces the traditional wedge gate valve structure. By having separate sealing mechanism components, it ensures a steadfast seal even under temperature-induced deformations without the risk of jamming due to high-temperature expansion.

When the valve opens, the sealing disk and valve seat disengage elegantly and rise due to the wedge block effect, which significantly reduces friction between sealing surfaces. This results in minimal torque, effortless operation, and prolonged service life. Our design effectively tackles issues like the large lifting force required for single gate start, easy sealing surface wear, poor sealing, short service life, and high-temperature opening and closing jamming, thereby substantially elevating the valve's sealing performance and extending its lifespan.}
