Reasonable price for Screw NPT/Bw/Sw Forged Steel A105 Swing Check Valve
Each pressing part of the combined seal ring has excellent performance.
friction
Small wear rate
Use two seal rings to prevent extrusion
The initial interference is designed to protect the seal performance at low pressure
Sealed rectangular geometry is stable -
IOS Certificate A105/F304/F316 Wafer Type Forged Steel Check Valve
The four lobed design provides twice the sealing surface of a standard O-RING.
Because of the double-sealing action,less squeeze is required to maintain an effective seal.The reduction in squeeze means less friction and wear which will increase service life and reduce maintenance costs.
Very good sealing efficiency. Due to an improved pressure profile over the X-Ring cross-section, a high sealing effect is achieved. -
18 Years Factory Cast Steel Check Valve Cast Check Valve
The guiding and sealing functions are achieved by the seals themselves in a very small space.
Suitable for use in mineral oil HFA, HFB and HFC fire resistant hydraulic oils (maximum temperature 60 ℃).
Seals are easy to install
Simple integral piston construction.
The special geometry of the NBR seal element allows installation without distortion in the groove. -
OEM/ODM Supplier API 6D Cast Steel Bolted Bonnet Swing Check Valve
Small installation groove, good sealing performance.
The operation is very stable due to the geometry of the sealing lip that holds the lubrication film best, and due to the use of rubber materials that have proved suitable on pneumatic equipment.
Small structure, so static and dynamic friction is very low.
Suitable for dry air and oil-free air, initial lubrication during assembly plays an important role in long working life.
Lip seal structure ensures proper function.
Easy to fit in sealed groove.
It is also suitable for cushioning cylinders. -
Free sample for RF Flanged Cast Steel CF3/CF8/CF8m Ball Check Valve
This seal pack is used for harsh and harsh operating conditions. Currently mainly used
In order to meet the needs of providing maintenance spare parts for old equipment.
V-type sealing group EK type,
The EKV can be used for pistons with pressure on one side, or
A “back to back” installation is used for sealing systems with pressure on both sides of the piston.
• Able to withstand extremely harsh conditions
- Long service life
• Can be optimized to adapt to the use of the corresponding equipment
• Even if the surface quality is poor, it can meet the sealing requirements for a period of time
• Not sensitive to contamination of hydraulic media
• There may be occasional leakage under certain conditions for structural design reasons
Occurrence of leakage or friction.
