Dwyer Instruments WE04 | 2-Piece flanged stainless steel ball valve
Genuine Dwyer Series WE04 ball valve from General Tech Services LLC, Saudi Arabia, with free Saudi Arabia shipping available.
Part No. WE04
Product Overview
The Dwyer Series WE04 is a 2-piece stainless steel ball valve with flanged end connections, designed for process isolation and control applications. Its flanged configuration provides a secure, bolted connection for compatible process piping and larger pipework installations.
The valve features a blowout-proof stem, reinforced PTFE (RTFE) seats and PTFE seals and packing, together with a 316 stainless steel (CF8M) ball. It can be supplied as a manual valve or configured with direct-mounted electric or pneumatic actuators.
Electric actuator options include weatherproof or explosion-proof versions, various supply voltages, two-position control and 4–20 mA modulating control. Electric actuators feature thermal overload protection and a permanently lubricated gear train.
Pneumatic actuator options include double-acting versions requiring 40–115 psi and spring-return versions requiring 80 psi, with a maximum pneumatic supply of 120 psi. The actuators use anodized and epoxy-coated aluminium construction and mount directly to the valve for a compact assembly.
Limit switches can be fitted directly to the valve for remote position indication, including manual valve configurations. Provide the required valve size, media, pressure conditions and actuation requirements so the exact model configuration can be confirmed.
