hydraulic fittings manufacturers - Parher

hydraulic fittings manufacturers Parher come in a variety of styles for many different hoses and applications. Please check carefully to select the right fitting for your application, and review the manufacturer's crimp specifications before assembly. Improper hose assembly may lead to hose failure and/or serious injury. Braided Hose Fittings provide over-the-cover crimp performance at an economical price, when compared to similar fittings, like U Series Hose Fittings. Braided Hose Fittings are designed for use with most 1-wire and 2-wire hydraulic hoses. We offer a variety of hose clamps and ferrules for most applications.

high pressure steel wire braided hose

high pressure steel wire braided hose use:
Steel wire reinforced hydraulic rubber hose mainly used for mine hydraulic support, oil exploration, suitable for construction, lifting and transport, metallurgy, forging, mining hydraulic hose equipment, ships, injection molding machinery, agricultural machinery, machine tools and various industrial sectors of mechanization and automation of hydraulic system has a certain pressure and temperature based (such as mineral oil, soluble oil, hydraulic oil, fuel oil, lubricating oil) liquid, water-based liquid (such as emulsion, oil-water emulsion, water), gas and liquid transmission purposes.

delivery valve and return valve operation

Delivery valve in the raised test sets can be opened a little bigger, so test sets the fastest rise, reducing overhead time trial. When the sample should pay attention to manipulate the Netherlands, according to the sample size must be adjusted for loading speed parher reusable hydraulic hose fittings should not rise too fast, so that the sample is under attack, should not be shut down for no reason, so that the sample suffered a sudden drop in load, thus affecting electronic universal testing machine test data accuracy. If the yield point make the specifications or other special test cases need to repeatedly increase and decrease the load, should also smooth operation.
Parher return valve in the sample, it must be closed, not allowed to have the oil to drain back to the specimen fracture, delivery valve should be closed, and then slowly open the oil return valve, remove the load and make testing machine piston back down to its original position, so that the oil back to the tank, you should note that the delivery valve handwheel Do not overtighten to avoid damage to the tip of the needle oil, oil return valve hand wheel must be tightened, because of the oil has a parher reusable fittings larger needle tip obtuse So easy to damage.

parher wire braided hydraulic hose pipe clamps

Parher Valve is mainly used in the sewage treatment plants, power plants, mining and other industries in this industry are mainly sewage treatment, generally exclude industrial plant hydraulic fittings effluent can be used to pinch valves, and some manufacturers also choose use float valve. The main reason why the valve is using pipe clamps pipe clamp valve does not impede the flow, the flow resistance is small, easy to sewage effluent will not be blocked. put on the top half of the folder, and then fixed with screws, you can locking cover to prevent it from turning. Then install a second pipe clamps. Hydraulic hose clamps used in life is relatively small,flat seal metric hydraulic fittings tube clamp valve we usually use are very simple valve. However, in industry or other industries is still relatively widely used.

Role valve Hydraulic hose pipe clamps

Parher hydraulic valve block is mainly used in the sewage treatment plants, power plants, mining and other industries in this industry are mainly sewage treatment, generally exclude industrial plant effluent can be used to pinch valves, and some manufacturers also choose use float valve. The main reason why the valve is using ferrule pipe fitting valve does not impede the flow, the flow resistance is small, easy to sewage effluent will not be blocked. put on the top half of the folder, and then fixed with screws, you can locking cover to prevent it from turning. Then install a second pipe clamps. Hydraulic hose clamps used in life is relatively small, tube clamp valve we usually use are very simple valve. However, in industry or other industries is still relatively widely used. Pipe clamps are more valves used in industry, industry waste water often contains a lot of impurities such as particles and powders, so it will be difficult to exclude the pipeline when there exclude some chemical related industries and sewage will corrosion performance, pipe clamps pipe valve is the best choice. important is its low maintenance costs, the design is simple, even if the external environment is very harsh and will not be affected.

Hydraulic pipes are larger diameter hydraulic hose

It is important to distinguish what type of hydraulic machines is being connected in the system to determine what fittings are appropriate.
hydraulic hose are seamless precision pipes specially manufactured for hydraulics. The hose have standard sizes for different pressure ranges, with standard diameters up to 100 mm. hose lengths are interconnected via flanges, welding nipples, flare connections, or by cut-rings. Direct joining of hose by welding is not acceptable since the interior cannot be inspected.
Hydraulic pipes are larger diameter hydraulic hose. Generally these are used for low pressure applications or when hydraulic hose are not available. They can be connected by welds or threaded connections. Because of the larger diameters the pipe can usually be inspected internally after welding.
Hydraulic hose is graded by pressure, temperature, and fluid compatibility. Hoses are used in applications where pipes or hose are not suitable, usually to provide flexibility for machine operation or maintenance. The hose consists of multiple layers of rubber and steel wire. Hydraulic hoses generally have stainless steel fitting swaged on the ends. The weakest part of hydraulic hose is the connection of the hose to the fitting, which is why proper fitting selection and installation is essential in high pressure applications.

Parher is committed to providing hydraulic fittings and adapters

Parher is committed to providing the highest quality in everything we do. That quality is evident in each of our products, supported by knowledgeable customer service and technical support from our field product specialists.
hydraulic fittings and adapters are perfect for applications and meet or exceed all SAE standards. We have the widest availability of hydraulic adaptors configurations in the industry. Fittings seal fluid within the hydraulic system by one of two techniques: all-metal fittings rely on metal-to-metal contact, while O-ring type fittings contain pressurized fluid by compressing an elastomeric seal. In either case, tightening threads between mating halves of the fitting (or fitting and component port) forces two mating surfaces together to form a high-pressure seal.
