Valve Stem Oil Seal :
Mitsubishi Seal Valve Stem is designed to ensure a reliable, high-performance seal on valves to preserve fluid and air pressure. Manufactured from American Iron and Steel Institute (AISI) grade 1018-1022 carbon steel, Mitsubishi Seal Valve Stem is designed to resist corrosion and feature an internal seal to provide both leakage prevention and long service life. The seal valve stem is an important part of any fluid control system, as it prevents fluid from escaping or entering the pipe or other conduit. Mitsubishi Seal Valve Stem features a precision seal, which prevents leakage and protects against pipe bowing or other pipe stress.
valve stem is an integral part of the valve system used to control the flow of liquid, gases and other media through pipeline systems. A valve stem is responsible for controlling the pressure and flow rate of media passing through the pipeline. The stem is usually connected to a handle, lever or screw mechanism to enable operational control.
The Valve stem is one of the main components of the valve, along with the bonnet, the body, and seat. Depending on the type of stem, it can be stem-and-yoke type, where the stem and a yoke connected to the stem is part of the valve body. The stem is responsible for the opening and closing of the valve and therefore works in much the same way as a plug. It is important to select the right type of valve stem as each type has different characteristics when it comes to sealing and flow rate regulation.

Features:
The Mitsubishi Valve Stem Oil Seal has a number of features that make it an essential part of any engine.
1. Valve Stem Oil Seal is made of a durable rubber material that is able to withstand high temperatures and vibrations that result from engine operation. This helps to ensure that the seal will stay strong and effective even after extended use.
2. Water Tight: The seal is designed to provide a tight and secure seal, which helps to prevent the oil from leaking out of the valve stem. The seal will also keep dirt and moisture out of the valve area, which helps to keep the engine running smoothly.
3. Easy to Replace: Valve Stem Oil Seal is simple to replace, and can be done without having to disassemble the entire engine. This makes it convenient and cost effective to maintain.
4. Compatible with Most Engines:Valve Stem Oil Seal is compatible with most engines, including those found in cars, trucks, and SUVs. This makes it one of the most versatile seals on the market.
Valve stem seals are made from a variety of materials, including nylon, PTFE rubber, steel, and synthetic rubber. Sometimes these materials are combined into a single sophisticated design. When synthetic rubber is used, there are three basic types: nitrile, polyacrylate, and Viton.
Nok-Cn factory provides you with high quality products.
Located in China since 1983, NNK SEALING PARTS CO., LTD. is a Valve Stem Seal supplier and manufacturer with more than 40 years of experence in the Seal Industry.
With more than 40 years experience, NNK is specialized in leading seal and oil seal manufacture. From oil seals, O-rings, to gaskets, and customized products, application industries include manufacturing, chemical processing, defense, water treatment and filtration, hydraulics, fluid power, heavy trucks, automobiles, aerospace, oil and gas, medical and For life sciences, food and beverages, a complete product line is available for customer needs and specifications.
Valve stem seals are made from a variety of materials, including nylon, PTFE rubber, steel, and synthetic rubber. Sometimes these materials are combined into a single sophisticated design.
There are two main types of valve stem oil seals: positive and non-positive. The positive type has two lips, one for the cylinder head side and the other for the valve stem side. They are predominantly used in older engines and have proven to be reliable in many applications. The non-positive type, however, has a single lip that seals against either the cylinder head or the valve stem side. This type is more commonly used and is the preferred option in modern engines due to its increased sealability and durability.
NNK valve stem seal Features:
Optional beaded lip design feature to provide lowest friction and power loss
Development to specific customer requirements
Consistent oil metering
Excellent resistance to oils/fuels and high temperatures
Benefits
Long term emissions control
Long service life
Optimum valve lubrication
Minimum valve guide wear for maximum valve train life
NNK can offer a range of standard valve stem seals, which provide the correct oil metering rate for many applications. This is true for diesel and gasoline applications as well as for intake and exhaust valves.
There are however, applications where the oil metering rate must be adjusted. The oil metering rate can be tuned to the exact requirements of a specific engine by changing defined design parameters of the sealing lip.
A sophisticated adjustment of seal lip design and contact load allows not only for modification of the average oil metering rate of a valve stem seal, but also for targeted tuning to support lubrication in defined engine application or load conditions.
Performance of the valve stem seal
Our valve stem seals are designed and validated to meet even extended durability targets of the engine. Dedicated FKM rubber material with widely proven performance is being used for standard applications, special material for the most aggressive oils and combustion residues is also available.
NNK valve stem seal design:
Positive seals : Attach to the valve guide boss. They work like a squeegee, wiping and metering oil on the stem as it passes through the seal.
Deflector seals: Deflect oil away from the valve stem. Also called umbrella seals, they move with the valve stem to shield the valve guide from excess oil.
Stem Seal Materials: Nylon, Teflon, Steel, and Synthetic Rubber (NBR, Polyacrylate, and Viton).

NNK and valve stem seals:
In order to prevent premature hardening and rupture due to insufficient heat resistance of rubber seals, NNK guarantees the service life and ensures that the engine is in a lubricated state. The materials we choose are based on the use environment of the seals and the characteristics of the materials themselves. The oil seals produced have high-quality properties such as high temperature resistance, wear resistance, and long service life. Currently, Viton has excellent heat resistance (up to 450° F) and abrasion resistance and is the material of choice for most valve stem seals. If you need replacement, buy new valve seals,please contact us.
