Steel swing check valve H44X-10/16-type check valve

Steel swing check valve manufacturer Zhejiang Golden Titanium Valve Manufacturing Co., Ltd. is a professional production, manufacturing factories, has certain advantages in price, quality, after-sales, logistics, shipping and so on. Swing check valve cast steel model H44X / H, HH44X / H valve, made of steel, so called steel check valves, check valves and cast iron check different prices, Cast iron check valves are generally applicable to the caliber of less than DN800 caliber less steel valve caliber can do DN2000. Specific details, please consult the titanium valves: 15167719797, dedicated to provide you with quality service! Fluid pressure cast steel check valve allows the valve from the valve seat sealing surface lift, open channel flow, when the medium reflux valve down to the seat, the flow channel is closed. The general level of cast steel check valve installed in the pipeline, installation or vertical installation options depending on the product model level. Steel valve concept: There are two kinds of cast steel valve body cover design in the form of connection: The first one is bolted forged steel valve body cover, in this connection in the form of valve design, the valve body and bonnet bolted, spiral wound gasket seal, the advantage of ease of maintenance; second body cover seal welded forged steel valve, in this connection in the form of valve design, the body and bonnet with screw connection mosquito, whole welding seal, the advantage of no leakage. Forged steel check valve in the form of closure were also shaped, needle-shaped, spherical, you can use our reasonable valve according to the actual situation. Check by structural steel division: can be divided into the lift valve, swing check valve and butterfly valve three. Vertical lift check valve can be divided into two kinds and straight. Swing check into a single lobe, double valve type and Orange Peel three. Butterfly valve for double butterfly valve, butterfly single lobe, check the connection over several forms can be divided into threaded, flanged, welded and clip-on connection of four. Cast steel check valve installation should note the following: 1. Do not check valve in the pipeline bear the weight of a large check valve should be self-supporting, so that the pressure generated from the piping system impact. 2, note the direction of flow of the medium should be consistent with the direction of the arrow on the valve installation. 3, the vertical lift check valve should be installed in a vertical pipe. 4. The level of valve lift check valve should be installed in horizontal pipelines. Steel valve structural features: bolted bonnet, swing and lift valve metal sealing surface. Body and bonnet connection form Class150 ~ Class900 using bolted bonnet; Class1500 ~ Class2500 pressurized seal bonnet. Valve cover gasket forms Class150 ~ Class300 valve made of stainless steel graphite spiral wound gasket; Class600 available stainless steel check valves can also be used graphite spiral wound gasket metal ring gasket; Class900 check valve can be used metal ring gasket, Class1500 ~ Class2500 check pressurized seal metal ring. Seat valve seat is usually forged carbon steel materials, seat sealing surface spray carbide according to customer requirements, NPS≤10 '' The use of separate check-in threaded seat, if the user need to weld the seat structure is also available; NPS≥12 globe valve seat structure using welding; stainless steel valve seat generally using integrated or directly on the body after the welding process carbide seat. If you have the demand, stainless steel valve seat may also be split into threaded and welded seat structures. Structural features large diameter valve steel swing check valve is designed with rings for easy lifting. Bolted bonnet flange gasket types can be selected according to the different pressure levels; CLASS600 pressure check valve can be self-tight seal structure. Valve stopper, preventing the valve in the open position is too high and can not be closed. Solid pin mounting precision, high strength, to ensure that the performance and service life of the valve rocker has sufficient strength, there is sufficient freedom to facilitate valve is closed off. Valve has sufficient strength and stiffness, valve sealing surface can be customized welding metal materials or non-metallic material inlay. Ordering Instructions: 1.
