Product Information

Universal Bimetallic Steam Traps

Type TS, TSF & SF with Cage Unit, Air Vent, Check Vale, Strainer & Optional Temperature Controller.

  • Forged Valve body and cover offer the advantages of high strength structural integrity and reliability that make it an ideal choice of steam service.
  • Stainless Steel Trim
  • Cage Unit. The advanced cage unit design in Velan Steam Traps combines a bimetal element, hardened Rc 58 min. ball valve and a Stellited seat area all in one factor-tested assembly. Replacement of all wearing parts can be achieved in less than two minutes, with the trap remaining on-line.
  • Stellited Seats. Al Velan valve seats area Stellite faced to increase their resistance to high degree of wear through velocity of flow, dirt and scale.
  • Integral Strainer. Stainless steel screens are integral in all three models to protect the trap operating mechanism from damage by dirt or scale. No extra fittings or installation costs are required. Free strainer area minimum 5 to 1. Perforation is 0.031" (0.8mm).
  • Universal Operation. The individual segments of the bimetallic element act consecutively, developing forces in close relation to the saturated steam curve. This permits sensitive, efficient trap operation at all pressures from 1 psi to maximum, without orifice change or adjustment.
  • Silent operation - no violent line shocks.
  • Positive closing. Every Velan steam trap closes tightly on saturated steam temperature. Positive closing for long periods on dry superheated steam has enormous advantages in power plant and marine services.
  • All-positive operation simplifies piping layout.
  • Freezeproof. Velan traps do not require a reservoir of priming water in the body to operate. When installed vertically with inlet on top, they drain completely when cold, and are freezeproof without insulation.
  • Positive condensate drainage for process work.

Velan Piping King Package Units

The piping King Package unit fitted with a bypass, enables the steam trap to be isolated from the system allowing routine maintenance to be carried out.

The unit consists of:

  • The unique patented Universal Steam Trap with integral strainer and check valve.
  • Two high-quality bonnetless forged steel special stop check globe valves mounted on either side of the trap.

The valves are connected by the bypass pipe, enabling the steam trap to be isolated while the steam flow is maintained.

Piping King units are used extensively in power stations, marine and similar applications where continuous operation is essential during routine maintenance.

Velan Monovalve Float Bimetallic Steam Traps

Type MFT/MFTS for Positive Drainage of Unit Heaters & Process Equipment. A Complete Unit: Built-in Strainer, Check Valve, Air Vent & Optional Bypass Shutoff.

  • Positive closing and condensate drainage. The bimetallic element is a function of the saturated steam curve and its sensitivity to the temperature change assures an immediate reaction to both steam and condensate for the entire pressure range. At saturated steam temperature the valve is closed as on a standard temperature the valve is closed as on a standard bimetallic steam trap, however, in this type of condensate build-up even at saturated steam temperature is discharged at the same rate. As it reaches the trap, the float becomes buoyant and opens the valves mechanically.
  • Stainless Steel Float & Trim
  • Simple Installation. Multiple inlet and outlet connections facilitate installation.
  • Integral strainer. Stainless steel screens are integral to protect the trap operating mechanism from damage by dirt or scale. No extra fittings or installation costs are required.
  • Integral check valve operation. The main valve acts a check valve preventing back flow.
  • Stainless steel pivots. Assure adequate protection against wear.
  • Seat stellite faced to increase resistance to high degree of wear through velocity of flow, dirt and scale.
  • Guaranteed against water hammer. The down-stream valves acts as a release valve on the excess water pressure without damage to internal parts.
  • Freezeproof installation without insulation - complete drainage when cold.

Velan Thermodynamic Steam Traps

Type HPTD, PTD & VTS with Stainless Steel Hardened Floating Disc.

  • Stainless steel hardened floating disc, ground and lapped with seat replaceable in line.
  • Gaskets are spiral wound, stainless steel with graphite. Trim is stainless steel.
  • Valve seats Stellited. Most Velan valve seats are Stellite faced to increase their resistance to the high degree of wear through velocity of flow, dirt and scale.
  • Integral strainer. Stainless steel screen are integral in all three models to protect the trap operating mechanism from damage by dirt or scale. o extra fittings or installation costs are required. Free strainer area minimum 5 to 1. Perforation is 0.031" (0.8mm).
  • Silent operation - no violent line shocks.
  • Positive closing. Every Velan trap closes tightly on saturated steam temperature. Positive closing for long periods on dry superheated steam lines has enormous advantages in power plant and marine service.
  • All-position installation simplifies piping layout.
  • Freezeproof installation. Velan traps do not require a reservoir of priming water in the body to operate when installed vertically with the inlet on top, they drain completely when cold, and are therefore freezeproof without insulation.
  • Positive condensate drainage for process work.
