Products Introdcution
This kind of valve is component of body, gate, stem, left and right nuts, bed, actuator, etc, and there are two kinds of electric blind plate valve, PN 1.5Pa, 2.5Pa.
First, this kind of valve is component of left and right body, circulator sector gate and nut.
Two, use three-point lock, circulator sector gate to component.
Third, long series blind plate vale with good sealing, non-leakage, strong flexibility, long life, etc. comes from short ones which one stainless steel corrugated tube is added.
Design Features of
Goggle Valves Type 1:
• Valve approved to “Man-safe”standards
(goggle valve - openwork structure)
• The design provides 100% shut-off of media
flow
• Total separation of the gas main in the closed
position, thus ensuring no passage of the
media from the upstream to the downstream
gas main, i.e. “Man-Safe” isolation
• Uniformly arranged clamping/unclamping
hydraulic rams on one side of the valve body
• Valve body with one movable and one fixed
body sealing seat
• Goggle plate seating/clamping is of
mechanical pressure effected by the spring
package within the hydraulic rams. Opening/
unclamping is effected by hydraulic pressure
onto the rams
• Dual circuit hydraulic systems available
• Open structure or totally enclosed design
• Venting to atmosphere of totally enclosed type
in closed position
• Valve actuation in accordance with customer’s
requirements (electr./hydr./pneum./man.)
• Very low maintenance requirement
• Pressure rating up to PN 6
• Operating temperatures up to 1100 °C (2000 °F)
• Nominal diameters up to 5000 mm (200 inch)
• Other sizes or operating conditions on request
