Stainless Steel Food Grade Sanitary Tri-clamp Angle Seat Valve
Pneumatic valves are operated by a pilot medium under pressure, usually compressed air but also oil or water. The valve is equipped with a pneumatic actuator supplied by a three-way solenoid valve. The pressure of the pilot medium enters the actuator cylinder and acts on the piston, which allows the seal to open or to close through the stem. The return of the seal into its rest position is usually achieved by a return spring that can be found in the pneumatic actuator.
- Model: HK17
- Size Range: 1/2''~4''
- Pressure Range: 0~1.6MPa
- Material: Stainless Steel
COVNA HK17 pneumatic piston angle seat valve can display of valve opening or closing position. External pneumatic pilot can increase service life and maintenance free.There is a self-adjusting gland between the overflow port and the sliding block, which can improve the sealing performance. Valve body angle seat structure, which can achieve large flow (especially compared with ordinary stop valve). Compact structure, fast response.
The product is made of stainless steel and polytetrafluoroethylene. It can be used in most gas, liquid, steam and corrosive occasions. It has a radiator to protect the actuator. It ensures a long service life of the valve.
There are single acting and double acting. Single action (pneumatic head is usually a hole); working principle; according to the function of spring return to open and close, it is divided into normally open type and normally closed type.
Double acting (pneumatic head usually has two holes); working principle: air supply controls its switch. (according to the customer’s requirements, double action plus spring return can also be selected for more accurate control)
