Product Description

Product Description

<sup>Our innovative Spring Loaded Double Parallel Sliding Gate Valve is a marvel of engineering excellence, offering a notable advantage over traditional wedge gate valves. This cutting-edge design boasts a reduced operating torque and a more compact drive size, delivering outstanding efficiency and ease of use. At the heart of this remarkable valve lies an INCONEL butterfly spring, chosen over the conventional coil spring, ensuring simplified assembly within the valve body. The ingenious compensation structure design effectively prevents jamming, even under challenging high-temperature conditions, by skillfully countering issues of adhesion and wedge extrusion. Both the valve plate and seat surfaces receive extraordinary hardening treatments through state-of-the-art techniques such as hard alloy overlay welding and surface spraying with Co-Cr-Ni alloy, WC, boron, and more. This exceptional surface treatment not only equips the valve with self-cleaning capabilities but also endows it with impressive surface hardness reaching up to HRC90 or higher.

Versatility meets precision with our Spring Loaded Double Parallel Sliding Gate Valve, designed for seamless integration with a variety of actuators. Whether you opt for pneumatic actuators, electric actuators, electro-hydraulic actuators, or manual actuators, this valve delivers consistent performance and adaptability to meet your specific operational needs.</sup>

^{Experience the physics of sealing power-where higher pressure means higher sealing force, ensuring reliability under pressure.
For environments characterized by high or fluctuating temperatures, our recommendation is clear: utilize graphite pressure sealing gaskets in lieu of standard soft iron gaskets, perfect for enduring high-temperature cycles.}

Double Parallel Sliding Gate Valves

<sup>This advanced valve takes a leap forward by incorporating a sealing structure of two parallel gates with a wedging device, replacing traditional designs. The separation of sealing components ensures unwavering performance, even amid temperature-induced deformations, thus eliminating issues of jamming from thermal expansion.

Upon opening, the innovative design ensures the sealing disk and valve seat smoothly disengage and rise, minimizing friction and reducing torque for effortless operation. This design revolutionizes traditional challenges like significant lifting force, rapid sealing surface wear, and jamming during high-temperature operations, thus extending the valve's operational life and elevating its sealing efficiency.</sup>
