Valve size DN80, pressure rate PN16, flanged end, raised face, the pipe flange as per GOST 33259-2015 for E, floating ball construct. The ball valve is used for shutoff purpose on-off type, main part material is austenic stainless steel: body ASTM A351 CF8, ball ASTM A182 F304, stem ASTM A182 F304, seats material PTFE. It’s full bore type valve. With firesafe design. the valve leakage class is as per GOST 9544 - A, valve operated by single action pneumatic actuator.
Refer to below detail description of concentric butterfly valve :DN200 rate PN16 wafer type, clamped between flanges, the flange standard GOST 33259, the valve is operated by electric actuator, material body material carbon steel WCB, disc stainless steel CF8, shaft stainless steel. The actuator is 380V / 50Hz / 3ph, no explosionproof, open / close type, with integrated limit switches, integrated torque switches, with manual override, IP67, for -40degree C, with cable gland .
Size PN200, pressure rate PN10, wafer type, clamping between flanges according to EN1092-1, the valve is three eccentric type. The butterfly valve is used for high temperature with radiator design. The material body material stainless steel A351 CF8, disc material stainless steel A351 CF8, stem SS, disc sealing ring SS304+graphite laminated.
The safety valve is a safety protection valve. Its opening and closing parts are normally closed under the action of external force. When the pressure of the medium in the equipment or pipeline rises and exceeds the specified value, it will automatically open. It is prevented by discharging the medium to the outside of the system. The pressure of the medium in the pipeline or equipment exceeds the specified value.
As per below detail description for the soft seat butterfly valve :DN250 rate PN16 type wafer end, clamped between flanges, the flange standard GOST 33259, the valve is motorize electric actuator operated, material body material ductile iron, disc material stainless steel CF8, shaft material stainless steel. The actuator is 380V / 50Hz / 3ph, no explosion-proof option, open / close type, with integrated limit switches, integrated torque switches, with manual override, IP67, for -40degree C, with cable gland .
