General information:

Trumbull Mud Valves are designed for use in draining large volumes of ﬂuids by means of static head pressure.

They are particularly useful in reservoirs, and in tanks of water and wastewater treatment plants, for normal

operations, and when draining is required for maintenance or cleaning.

These valves are generally intended for low pressure applications; however, please consult Trumbull for special

requirements, such as high head pressure, or back pressure applications.

There are two different Mud Valve models available: Cast Iron, and Cast Stainless Steel. The standard Cast Iron

model uses brass seats in the body and gate; however, resilient seats are also available as an option. The cast

iron assembly features bronze stems and bronze threaded guides for use in submerged installations. The fasten-

ers are stainless steel to prevent corrosion during the life of the valve.

Cast Iron, Non-rising Stem Type Valve

The Cast Stainless Steel model uses SBR seats in the gate (other seat materials are available), and seals against

the stainless steel base ﬂange. All metallic components of the Cast Stainless Steel mud valve are Type 316 stain-

less steel. The stem has a proprietary coating to eliminate galling and provide decades of service life.

Cast Stainless Steel, Non-rising Stem Type Valve

Trumbull mud valves can be furnished with extension stems of carbon or stainless steel. The extension stems can

then be operated thru a 2” operating nut in a ﬂoorbox (see illustration on page 4), or with an indicating ﬂoorstand.

Position Indicators are also available for installation in the ﬂoor (see page 10), or over an open tank (see page

11.)

When ordering extension stems, the material type must be speciﬁed along with either the overall length required,

or the distance from the face of the mud valve ﬂange to the top of the handwheel, the 2” nut, or to the base of the

ﬂoorstand.

Page 3 of 12

Installation:

To insure proper operation of the Mud Valve, the following instructions must be followed:

1) The Mud Valve must be mounted to a mating ﬂoorpipe having a standard 125# ﬂange.

The mounting ﬂange should be recessed below the ﬂoor surface; the mud valve base seating surface

should be below the ﬂoor surface for complete draining of the ﬂuid.

The ﬂange must be installed level to provide vertical alignment for an extension stem.

Note: The Mud Valve ﬂange is drilled in accordance with the ANSI 125# template on all sizes; however,

one hole under each Yoke leg is not available for fastening to the mating ﬂange.

Fasteners for mounting are not furnished but can be ordered separately.

2) The area surrounding the mounting ﬂange should be clean, and clear of obstructions.

Typical installation is shown on the following pages 4 and 5.

3) Prior to the installation of the mud valve, check the bottom of the valve ﬂange for any adhering materials,

such as wood or packing debris, and for any visible damage.

4) Open the valve and clean the seating surfaces.

5) Operate the valve before installation to make sure it operates properly and was not damaged during ship-

ment or handling.

6) Do not use chains or other lifting devices on the stem or the bronze seats as this could deform the

threads, bend the stem, or damage the sealing surfaces.

7) For proper lifting, use a nylon strap of sufﬁcient lifting capacity, and lift from under the yoke, as shown in

the ﬁgures below.

Proper lifting of mud valves, using a sling

Non-rising Stem Type Non-rising Stem Type

8) Install the valve to the mounting ﬂange using a full face, 1/8”, rubber ﬂange gasket with the proper sized

bolts, or studs and nuts, for this size valve.

9) Tighten fasteners using a star tightening pattern. Uneven or over tightening could cause excessive leak-

age.

Note: Mud valves are not designed to be bubble-tight, and are not covered by an AWWA standard. Some

leakage may occur.

10) Check for obstacles between the gate and the yoke, then cycle the valve fully open and fully closed, to

make sure it opens and seals properly.

11) Complete the installation of related accessories such as extension stem, stem guides, ﬂoorstand or ﬂoor

box, as speciﬁed by the design engineer.

Trumbull Mud Valves are designed primarily for use in

settling tanks of water and wastewater treatment plants.

Their intended use is to drain tanks for maintenance or

cleaning. They are for low pressure applications only;

consult Trumbull for special requirements.

Mud Valves are furnished with a 2”square operating

nut; however, they can be supplied with optional

extension stem or handwheel (see page G-5).

This valve series uses bronze seats in the body and

gate (also available with resilient seat). The cast iron

body assembly features manganese bronze stems

and guides for use in submerged installations.

The fasteners are furnished in stainless steel to

prevent corrosion from years of submerged service.

Nuts, bolts and gaskets for mounting to ﬂoor pipe are

NOT furnished but can be ordered separately. Ductile

iron components are coated with Tnemec N140-1211

epoxy, per NSF 61.

See pages G-28 and G-29 for drawings.

Trumbull Mud Valves are designed primarily

for use in settling tanks of water and wastewater

treatment plants. Their intended use is to

drain tanks for maintenance or cleaning.

They are for low pressure applications only;

consult Trumbull for special requirements.

For applications requiring more corrosion

protection than cast iron, the yoke,

ﬂange, guides and gate of these

Mud Valves are cast from Type 316

stainless steel. The one-piece, Type

316 stem has a permanently bonded

coating to protect against galling for

a lifetime of maintenance-free operation.

Cast components eliminate corrosion problems frequently

caused when stainless steel is welded. Castings are

passivated after machining, per ASTM A-967. Heavy-duty

design incorporates generous wall thicknesses and stem

diameters for maximum strength and corrosion protection.

Seat is SBR rubber for positive shutoff. Mechanically retained

seat is ﬁeld-replaceable. Fasteners are Type 316 stainless.

See pages G-32 and G-33 for drawings.

Nuts, bolts and gaskets for mounting to ﬂoor pipe are

NOT furnished but can be ordered separately.
