Lock balance valve

Overview of FQ all weather breathing valve: GFQ all-weather breathing valve is used on oil and liquid tank to remove the positive pressure and negative pressure gas in the tank, so that the liquid in and out of the tank is convenient. If there is no breathing valve on the tank, the liquid in and out of the tank has certain obstacles, which is likely to cause tank deformation and vibration. The product has reasonable design, simple structure and convenient use; It is an indispensable product of storage tank.

The XUVAL-158 series is a magnetic driven high-temperature vortex pump that delivers circulating media that do not contain particles or fibrous liquids. The pump has a beautiful appearance, low vibration, and is suitable for circulating high-temperature heat transfer oil within 350 and hot water within 180.

Overview of Pneumatic Wafer Type Hard Seal Butterfly Valve: D673H pneumatic hard-sealed butterfly valve features This valve adopts a three-eccentric sealing structure, the valve seat and butterfly plate are almost wear-free, and it has a tighter and tighter sealing function. The sealing ring is made of stainless steel, which has the dual advantages of metal hard seal and elastic seal. It has excellent sealing performance, corrosion resistance and long service life regardless of low temperature and high temperature.

ANSI 150LB Globe valve also known as the door valve, belongs to the forced sealing valve, so when the valve is closed, must apply pressure to the disc, in order to force the sealing surface leakage.When the medium under the disc into the valve, the operating force to overcome the resistance, is the friction of the valve stem and packing and by the pressure of the medium produced by the thrust, the force to close the valve is greater than the force to open the valve, so the diameter of the valve stem to be large, otherwise the valve stem bending fault will occur.

“Item is in very good condition. Item is dirty and has some discoloration from warehouse storage and freight. See pictures for reference.”

Product Introduction: 1、 Product details of micro resistance slow closing butterfly check valve: Product name: Micro resistance slow closing butterfly check valve Product features: Suitable for medium pipelines such as clean water, sewage, and seawater with a nominal pressure of 1 MPa and a medium temperature of ≤ 80%, as well as pressurized water supply and drainage

Plug valves are shutoff or plunger shaped rotary valves that open or close a valve by rotating 90 degrees so that the port on the plug is identical to or separate from the port on the body.

The exhaust valve is used for pipeline exhaust in independent heating systems, centralized heating systems, heating boilers, central air conditioning, floor heating, and solar heating systems. Because water usually contains a certain amount of air, and the solubility of air decreases with the increase of temperature, gas gradually separates from the water during the circulation process and gradually gathers together to form large bubbles or even gas columns. Due to the supplementation of water, gas is often generated.

Overview of D363H/W Butt Welding Hard Seal Butterfly Valve: D363H butt-welding hard-sealed butterfly valve is widely used in metallurgy, electric power, petrochemical, water supply and drainage, municipal construction and other industrial pipelines with medium temperature ≤ 425℃. It adopts precision J-shaped elastic sealing ring and three-eccentric multi-layer metal hard sealing structure for adjusting flow and carrying and breaking fluid. The valve seat and disc sealing surface are made of different hardness and stainless steel, which has good corrosion resistance. Long life, this valve has a two-way sealing function, and the product meets the national GB/T13927-92 valve pressure test standard.
