Series S-8C and S-6N is a robust, compact and lightweight control valve with a pneumatically operated, easy field reversible multi-spring diaphragm actuator. The actuator can be equipped with a fully enclosed emergency handwheel which is in compliance with general safety precautions (1).

The S-8C and S-6N series has a double-life (quick-changeable trim combination) with the option of a double-side use by reversing the seat ring (10). Because of its simple geometry the valve seat can be economically produced in different materials such as hardened and stellited steel, ceramic, Tungsten carbide, etc., with or without soft sealing. In comparison to conventional designs the speciality of the Ecotrol’s soft sealing is, that the PTFE-element is flexibly supported by an additional Elastomer O-Ring. Both sealing elements are located in the seat ring and not as usual in the valve plug. The additional metal-to-metal sealing of plug and seat ring ensures that the TFE-disc suitable for doubleside use is not plastically deformed by excessive loads. The remarkable difference between the common screwed-in seat ring and this unique quick-change(able) trim combination shown in the figure (fig1) works on the principle of retaining and sealing the seat ring in the valve body. With a screwed-in seat ring the sealing between seat and valve body is provided by the metal-to-metal contact of two conical faces.

The conical counterface in the valve body has a slightly different angle so that there is only a theoretical circumferential line contact. The required torque to screw-in the seat ring is individually different depending on the construction and the operating conditions. With the S-8C and S-6N series the seat sealing is done purely axial and achieved by the method of initial compression. The compression of the sealing elements (6, 11) is limited by the precisely sized recess in the body for containment of the flat gasket. This limits the gasket’s compressive loading and guarantees a perfect alignment between the sealing surfaces of plug and seat ring. The self-aligning seat ring (10) is held by the retaining cage (9). The tightness is achieved by transferring a portion of the bonnet-to-body bolting force via the retaining cage to the seat ring. The valve body (12), retaining cage, and seat ring are manufactured on special CNC-machining centres to meet the stringent tolerances of each part. This guarantees the required compression of the sealing elements. Excellent stem guiding is achieved by two special guide bushings (4, 8) located as far as possible from each other.

Ecotrol - Quick change trimSeries S-8C and S-6N

Another added feature is the standard spring energised stem seal configuration including a PTFE-V-Ring packing set (5) with an additional micro-sealing element and wiper ring (3).The PTFE-V-Ring packing set is pre-loaded by a stainless steel spring and pressed against the valve stem and the bonnet insert (7).The packing set acts as primary sealing and as wiper. The valve stem is guided at two locations right before and behind the stem sealing (5).In addition to the extremely reliable sealing performance even under varying operating temperatures, the stem sealing provides reduced static and sliding friction forces in comparison to conventional stuffing box packing.

Air to close

Multi spring actuatorThe pneumatically operated multi-spring diaphragm actuator is field reversible without the need of disassembly. This actuator is suitable for use with Namur smart positioners (without tubing) or the standard pneumatic / electro-pneumatic positioners with tubing.

During operation there is a minimal overpressure against atmosphere on the backside of the diaphragm plate (spring chamber) which guarantees that during stroke movement no ambient air can be sucked in the spring chamber. This protects the essential inner parts against aggressive atmosphere (like saline ambient conditions).

The springs are specially treated and suitable for more than 1 million cycles.

Angle drain valveSeries S404 / S405

The S404 Angle Pattern Drain Valve is designed for High Pressure Drain service. Typical applications for this valve are Reheater and Turbine Drain Lines.

The Single Stage Drain Valve (S404) design combines the advantages of a High Pressure Stop valve and the reliability of a Drain Valve design.

The valve has a Seat and a Parabolic plug which help to reduce pressure in Single Stage. Due to the unique design of the plug, the flow is kept away from the seat, preventing wire drawing at the valve seat.

The Spindle, Control plug and Seat are nitrided to resist erosion and wear.

The Plug and Seat are further stellited to increasing the wear resistance.

The Non Rotating Control plug and Spindle are manufactured from a single bar and thus ensure stability in operation.

The valve yoke is Dust Proof and is provided with roller thrust bearing for ease of operation. High-density pure graphite rings and Roller Burnishing of the spindle and stuffing box bore, eliminate leakage through gland packing. The Valve can be operated by a hand wheel or with an electrical actuator without modifying the yoke.

Buttweld and Socket weld ends are provided as the specification standard with Flanged end as special optional provision.

Bill of material for S404 / S405

The S405 Angle Pattern Drain Valve is designed for High Pressure Drain service. Typical applications for this valve are Reheater and Turbine Drain Lines and feedwater recirculation lines. These valves are designed for Pressure Drops as high as 2900 psig.

The Multistage Drain Valve (S405) design combines the advantages of a High Pressure Stop valve and the reliability of a typical Drain Valve design.

The valve has a Single seat with slots on the spindle which help to reduce pressure in multiple stages. Due to the unique location of the slots, the flow is kept away from the seat, preventing wire drawing of the valve seat. The seating area is further strengthen by stellite deposition at valve seat. The spindle, control plug and seat are nitrided to resist erosion and wear.

The control plug is guided throughout its travel by the seat

bush, eliminating the harmful effects of vibration. The slots in the control plug and those in the seat bush help maintain low noise levels when the valve is in operation.

The control plug and spindle are manufactured from a single bar to ensure stability in operation.

The valve yoke is provided with a roller thrust bearing for ease of operation.

High-density pure graphite rings and roller burnishing of the spindle and stuffing box bore eliminate leakage through gland packing.

The Valve can be operated by a hand wheel or with an electrical actuator without modifying the yoke.

Buttweld and Socket weld ends are provided according to specification standard with Flanged end as special optional provision.
