。 At the same time to take a short trip disc preset. By means of the valve at the bottom of the flange welding on the bottom of the tank and other vessels, for the alleviation of process media general export legacy phenomenon in vessels. body cavity is tightly closed circle of scouring and corrosion resistance, in the open valve flap, can try our best to take care of the body are not medium erosion, corrosion, and to execute special disposal, tightly closed circle to surface hardness HRC56 - 62, has the function of high wear resistance, corrosion resistance, the disc tightly closed according to the requirements cover all have cemented carbide surfacing, vice sees fit tightly closed and use line tightly closed, keep good tightly closed, and can prevent scarring. 2, all kinds of manual valves installed on the warm pipe, handle are not down. The strength to try, try to pressure for the nominal pressure of 1. Five times the continuous time not less than 5 min, valve shell, packing should be no leakage to conform to the standard. Suitable for use in sulfuric acid, hydrofluoric acid, phosphoric acid, chlorine, strong alkali, aqua regia artificially strong corrosive medium, etc. Feeding ball valve is used with a circular spherical stereo channels as open-close, spherical stereo with the valve rod rotation to achieve on-off movement. ball valve, the opening and closing is a porous spherical stereo, vertical to the axis of the channel rotate, thus achieve the objectives of the opening and closing the channel. Feeding valve body structure: mainly by the valve body, disc, tightly closed ring, valve stem, stents, valve gland, hand wheel, flange, screw nut, positioning screws and other parts. 3, installation position and height, the import direction must accord with the preset requirement, even who strengthen emergency. Was sex to try, try to pressure for the nominal pressure of 1. 1 times; Try to pressure trying to continuous time should accord with GB 50243 standard requirements, with disc tightly closed surface no leakage to conform to the standard. To make a switch or adjust, this product is suitable for use in various industrial produce liquid feeding, in all kinds of strong acid, alkali, salt and other corrosive medium can work beautifully. Lining fluoride feeding valve deem appropriate and use the fluorine molecular compound plastic lining as ball valves, and match them with the new with rod spherical stereo structure, coupled with its unique special elastic lips tightly closed type structure, make its have the common ball valves of various strengths, can in the large pressure difference and large temperature difference changes within the scope of Gao Yanmi sealing performance and low operating torque. Q: the use of feeding valve and install explained a: feeding valve is mainly used in the reaction kettle, the bottom of the tank and other vessels nesting, feeding, sampling, and no dead zone off operation. Free feeding Industrial Valves operation is convenient, open, flexible movement dependable; Disc assembly maintenance simple, tightly closed structure is reasonable, tightly closed loop transform is convenient and practical. Feeding valve performance and use: the operation is convenient, open free and flexible movement dependable; Disc assembly maintenance simple, tightly closed structure is reasonable, tightly closed loop transform is convenient and practical. 4, prior to valve installation the appearance of seizing, valve metal brand should accord with the current nation standard GB 12220 of 'general micro valve regulation. For office pressure is greater than 1. 0 MPa and play on ZhuGanGuan truncation utility valve, before installation should try of strength and tightness, conform to the standard rear must use. Feeding valve installation essentials: 1, the feeding valve in the pipeline should be ordinary water there is no danger. Feeding valve on the need of the actual state of things, put a default for the flat bottom structure, the body for 'V', and two workers Marine valve supply increase and decrease as a form of the disc. Notes to the order: The national standard) A, A: B: product name, model, nominal size medium and temperature, pressure range C: whether there is attachment, delivery time, and special requirements so that we can correct selection for you. Second, if the valve has been selected by design unit of our company model, please order according to the valves parameters directly with our sales center.

The importance of gate valve has increased as resilient valve have become a must in our daily life.
Deliver value to our customers by providing the most reliable and efficient products as water gate valve.
Although there are various available in the market (such as os gate valve, cast iron gate valve, and y gate valve), recent study results have made this os&y valve wedge gate valve a preferred wedge valve choice of the people.
