Product Description

Product Description

<sup>Introducing the state-of-the-art Pneumatic Cylinder Actuator Spring Loaded Double Parallel Sliding Gate Valves from SNT Machinery (Qingdao) Co., Ltd. This innovative valve design stands out from traditional wedge gate valves with its significantly reduced operating torque and drive size. At the heart of this engineering marvel is the integration of an advanced INCONEL butterfly spring in place of the conventional coil spring, ensuring seamless assembly within the valve body. The groundbreaking compensation structure ingeniously prevents jamming, a common issue in high-temperature environments, by mitigating adhesion and wedge extrusion. The valve plate and seat surfaces boast remarkable durability, thanks to hard alloy overlay welding and surface treatments with Co-Cr-Ni alloy, WC, or boron, achieving a remarkable surface hardness of HRC90 or higher. This feature not only enhances self-cleaning capabilities but also elevates the overall performance.

Tailored for versatility, the spring loaded double parallel sliding gate valve seamlessly integrates with a variety of actuation options, including pneumatic actuators, electric actuators, electro-hydraulic actuators, or manual actuators. Experience unparalleled adaptability and precision with our cutting-edge valve solutions.</sup>

Structural Features

 

Product Feature

 

^{Our Pneumatic Cylinder Actuator Spring Loaded Double Parallel Sliding Gate Valves boast a pressure seal bonnet, meticulously crafted with high-density pure graphite gaskets for utmost reliability.
An innovative overpressure protection device is seamlessly integrated into the bonnet, providing unparalleled security against excessive pressure.
Engineered with a spring preloaded flat gate valve, designed for optimal performance and efficiency.
Designed with a relatively wide valve seat and gate, ensuring maximum stability and operational excellence.
Outfitted with a precise limit device on the support rod, guaranteeing accurate operation and control.
Featuring an anti-rotation device on the valve stem, ensuring consistent and reliable functionality.
Crafted with differing hardness on both ends of the sealing surface to avert wear. The sealing surface features a meticulous hardness calibration (~5HRC): gate - STLG#, valve seat - STL12#.
Bonnet sealing is designed with an advanced conical structure for superior sealing integrity.
Engineered for bidirectional flow, offering versatility and adaptability in various applications.
Equipped with two thrust bearings and robust aluminum bronze sleeves for smooth, durable operation.
Designed with an available structure for bypass piping, enhancing flexibility and utility.}

Spring Compensated Valve Plate Assembly

Utilizes a graphite ring pressure self-sealing structure for enhanced sealing reliability.

^{The unique design ensures that as pressure increases, the sealing force correspondingly intensifies, guaranteeing optimal performance.
In environments characterized by high temperatures or frequent temperature fluctuations, we recommend substituting standard soft iron gaskets with graphite pressure sealing gaskets to ensure superior performance and longevity in high-temperature and frequent temperature cycle scenarios.}

Double Parallel Sliding Gate Valves

<sup>The cutting-edge Double Parallel Sliding Gate Valves feature a sophisticated sealing structure with dual parallel gates and a wedging mechanism, replacing conventional wedge gate valve designs. This integral separation of sealing mechanism components allows for flawless sealing even under temperature-induced deformation, ensuring reliability without jamming, even amidst high-temperature expansions.

During operation, as the valve opens, the sealing disk and valve seat first disengage and then elevate due to the wedge block effect, substantially minimizing friction on sealing surfaces. This results in less required torque, facilitating easy operation while extending service life. This innovative design overcomes challenges such as the large lifting force required for single gate initiation, sealing surface wear, poor sealing, reduced service life, and high-temperature operational jamming, thereby significantly enhancing the valve's sealing performance and overall durability.</sup>
